Apple rejection - We still noticed that the user is taken to the default web browser to sign in or register for an account, which provides a poor user experience.

## Issue
Apple rejected with below reason today. Please review and recommend the next step.

Guideline 4.0 - Design

We still noticed that the user is taken to the default web browser to sign in or register for an account, which provides a poor user experience.

Next Steps
To resolve this issue, please revise your app to enable users to sign in or register for an account in the app.
You may also choose to implement the Safari View Controller API to display web content within your app. The Safari View Controller allows the display of a URL and inspection of the certificate from an embedded browser in an app so that customers can verify the webpage URL and SSL certificate to confirm they are entering their sign in credentials into a legitimate page.

## Environment
* **Your Identity Provider**: `Azure`
* **Platform that you're experiencing the issue on**: `iOS`
* **Your `react-native` Version**: `~0.73.7`
* **Your `react-native-app-auth` Version**: `^7.1.3`
* **Are you using Expo?** No

首先检查 react-native-app-auth 中的 iOS 身份验证流程，以及 Azure 登录当前如何打开默认 Web 浏览器。将可用的 AppAuth 行为与 Safari View Controller 进行比较，然后确认登录和注册仍在应用内完成，并满足 Apple 提出的要求。
