Google SignIn: Getting ID Token for Server-side Auth #16613
Description
Steps to Reproduce
I started using Firebase Auth after I already had a custom OAuth impl in place, so in my previous app, I would authenticate the user on Firebase, but also request an ID Token from Google Signin https://developers.google.com/identity/sign-in/android/offline-access.
Is there currently a way to do this on google_signin? On Android, I would do something like SignIn.requestServerAuthCode(serverClientId).
