Error after signing in with apple

In out app we have log in with apple implemented through CustomAuth. Why not Web3Auth? Because it creates extra web view in the background.

So we log in with SignInWithAppleButton, and then pass the JWT to Web3Auth through CustomAuth. And now that we have CustomAuth implementation we have to stick to it, because `Web3Auth(params).login(W3ALoginParams(loginProvider: .APPLE))` does not lead to the same profile. Recently we updated from version 5 to version 11, and CustomAuth with apple started returning an error:

`Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=3 "The UIWindowScene for the returned window was not in the foreground active state." UserInfo={NSDebugDescription=The UIWindowScene for the returned window was not in the foreground active state.}`

Most likely it happens because apple login flow triggers a modal Safari-based login under the hood (via ASWebAuthenticationSession or similar), and this temporarily moves the app to the background or an inactive state while the Safari window is active. After a successful login Web3Auth wants to call a redirect back to app I guess, leading to an error because the app is still in the background while the apple's login sheet is still displayed.

*Please tell us exactly how to reproduce the problem you are running into.*

1. Press SignInWithAppleButton, and enter the appID and password
2. Pass SignInWithAppleButton's result to CustomAuth
3. Error

*Code*

this line causes the error:
`let torusLoginResponse = try await customAuth.triggerAggregateLogin(args: aggregateLoginParams)`

apple button, used to login with apple:
```swift
var appleButton: some View {
SignInWithAppleButton(.signIn) { request in
request.requestedScopes = [.email, .fullName]
} onCompletion: { result in
switch result {
case .success(let authorization):
viewModel.handleSignInWithApple(authorization: authorization) // call the method to pass this to CutomAuth
case .failure(let error):
print("Authorization failed: \(error.localizedDescription)")
}
}
}
```

handleSignInWithApple:
```swift
func handleSignInWithApple(authorization: ASAuthorization) {
let subVerifierDetailsArray = SingleLoginParams(typeOfLogin: .jwt, verifier: ApplicationTarget.current.appleLoginSubverifierName, clientId: Constants.appleLoginVerifierClientId, jwtParams: OAuthClientOptions(domain: "web3auth.au.auth0.com", verifierIdField: "email"))

let aggregateLoginParams = AggregateLoginParams(aggregateVerifierType: .single_id_verifier, verifierIdentifier: Constants.appleLoginVerifierId, subVerifierDetailsArray: [subVerifierDetailsArray])

let customAuthArgs = CustomAuthArgs(urlScheme: "roveapp://auth", network: .CYAN, enableOneKey: true, web3AuthClientId: ApplicationTarget.current.web3AuthClientId)

Task {
do {
let customAuth = try CustomAuth(config: customAuthArgs)
let torusLoginResponse = try await customAuth.triggerAggregateLogin(args: aggregateLoginParams)
let encoded = try JSONEncoder().encode(torusLoginResponse)
} catch {
DispatchQueue.main.async {
print(error)
}
}
}
}
```

Please create a minimal reproducible sample that shows the problem, and attach it below between the lines with the backticks.

```swift
import SwiftUI
import AuthenticationServices
import CustomAuth

@main
struct Application: App {

@UIApplicationDelegateAdaptor var appDelegate: AppDelegate

var body: some Scene {
WindowGroup {
appleButton
}
}

var appleButton: some View {
SignInWithAppleButton(.signIn) { request in
request.requestedScopes = [.email, .fullName]
} onCompletion: { result in
switch result {
case .success(let authorization):
handleSignInWithApple(authorization: authorization) // call the method to pass this to CutomAuth
case .failure(let error):
print("Authorization failed: \(error.localizedDescription)")
}
}
}

func handleSignInWithApple(authorization: ASAuthorization) {
let subVerifierDetailsArray = SingleLoginParams(typeOfLogin: .jwt, verifier: ApplicationTarget.current.appleLoginSubverifierName, clientId: Constants.appleLoginVerifierClientId, jwtParams: OAuthClientOptions(domain: "web3auth.au.auth0.com", verifierIdField: "email"))

let aggregateLoginParams = AggregateLoginParams(aggregateVerifierType: .single_id_verifier, verifierIdentifier: Constants.appleLoginVerifierId, subVerifierDetailsArray: [subVerifierDetailsArray])

let customAuthArgs = CustomAuthArgs(urlScheme: "roveapp://auth", network: .CYAN, enableOneKey: true, web3AuthClientId: ApplicationTarget.current.web3AuthClientId)

Task {
do {
let customAuth = try CustomAuth(config: customAuthArgs)
let torusLoginResponse = try await customAuth.triggerAggregateLogin(args: aggregateLoginParams)
let encoded = try JSONEncoder().encode(torusLoginResponse)
} catch {
DispatchQueue.main.async {
print(error)
}
}
}
}

}

**Smartphone (please complete the following information):**
- Device: simulator iPhone 16 pro max
- OS: iOS 18.3

**Additional context**
CustomAuth version 11.0.2

Could you please consider adding something like `customAuth.triggerAggregateLogin(...)` which simply returns the torusLoginResponse without trying to call any redirects or whatever relies on being in the foreground? Or if you have that already, could you please point me in the correct direction?
Thank you in advance for your help, have a great day!

Start with the provided minimal sample, the SignInWithAppleButton completion handler, and handleSignInWithApple, then run customAuth.triggerAggregateLogin(args:) on iOS 18.3 with CustomAuth 11.0.2. Compare the flow with the reported WebAuthenticationSession Code=3 logs; done means reproducing the failure and identifying a supported foreground-safe login behavior or documenting the limitation.
