Linking Google Account to Existing Firebase User

[liamberries]

Hello,

I am encountering an issue when a user attempts to sign in with a Google account that already exists in my Firebase database. Instead of successfully linking the accounts, the user is redirected to the following URL:

/api/auth/signin?error=OAuthAccountNotLinked

Is there a way to link the Google account with the existing Firebase user within the auth file? My goal is to provide a smoother user experience or a more customized UI for this route.

Any guidance or suggestions would be greatly appreciated!

Thank you!
