I created my first web app using Firebase and implemented user auth using FirebaseUI. In my Firebase console, I can see the Users table in the Authentication tab being created with a unique Identifier (phone number, e-mail). My Firebase project is also connected to my GCP project.

How can I see my Firebase app’s table of users in GCP? Ideally, I would like to have that in a Datastore service or similar. Is there a way to sync users between Firebase and GCP? I need that, to allow my backend application in Cloud Run can do a quick lookup (based on the user’s Identifier).

So far, I could only find a function to check if the user exists in the Firebase’s Users table directly:

from firebase_admin import auth, credentials

def is_user_in_firebase(identifier: str) -> bool:
    
    try:
        auth.get_user_by_phone_number(identifier)
    
    except auth.UserNotFoundError:
        return False
    
     else:
        return True
