Blazor Standalone Webassembly - Unable to configure multiple IdP with Azure AD

### Is your feature request related to a problem? Please describe the problem.

I have a **Standalone Client side Blazor Web Assembly** hosed in the Azure Static Web App.

Currently its configured to authenticate with Azure AD using MSAL.

// Add Msal
builder.Services.AddMsalAuthentication(options =>
{
builder.Configuration.Bind("LoginAd", options.ProviderOptions.Authentication);

// For linux apps specify issues expliclity

//
options.ProviderOptions.Authentication.Authority = "https://login.microsoftonline.com/common";

options.ProviderOptions.LoginMode = "redirect";

options.ProviderOptions.DefaultAccessTokenScopes.Add("openid");
options.ProviderOptions.DefaultAccessTokenScopes.Add("offline_access");
options.ProviderOptions.DefaultAccessTokenScopes.Add("profile");
options.ProviderOptions.DefaultAccessTokenScopes.Add("email");

}).AddAccountClaimsPrincipalFactory();

This enables me to authenticate any Microsoft work, school and personal account using standard auth routes.

`authentication/login`
`authentication/logout`

I need to add additional identity providers.

```
uilder.Services.AddAuthentication().AddOpenIdConnect( { idp1

uilder.Services.AddAuthentication().AddOpenIdConnect( { idp2

uilder.Services.AddAuthentication().AddOpenIdConnect( { idp3
```

I can add these services in the Program.cs but, how to tell the Blazor engine to initiate authentication with a specific IDP ?

Example:
`authentication/login/idp1`

### Describe the solution you'd like

The DI services enables adding multiple OpenId Connect IdPs, I want to pass certain hint so that the Blazor WASM engine `authentication\login` can initiate the authentication for a specific IdP.
