solved with Option 2: Switch to signInWithPopup()

Option 1: Update your Firebase config to use your custom domain as your authDomain only working with one authDomain, not working with {my-app}.web.app

Option 3: Proxy auth requests to firebaseapp.com same problem with Option 1

Option 4: Self-host the sign-in helper code in your domain This solution does not support Apple sign-in. I value supporting apple oauth.

Option 5: Handle provider sign-in independently Laborious, There are many high-priority development items right now, so we'll reconsider them later.
