When I click Firebase project it creates a Firebase project for me automaticaly and it sets some fields in Google Cloud Platform so when you go to Google Cloud and try to do the settings for Google authentication like branding of OAuth consent screen you see info there and you taught with yourself that setup is done automaticaly but when you code it out and test it it gives you popup closed by user error. After days of changing code and settings I finaly found out that Developer contact information is not set. How could I know? Dont set automaticaly or set it completely or at least give a clear error that your Developer contact information is not set. Why its like you try to suffer customers and users?
