'Firebase auth: problem with insert user on Google Sign-In in Android

I try to create auth with Firebase in my android project. after following the documentation, I can access user details like email or displayName but method signInWithCredential in firebase displays error.

code:

 private fun firebaseAuthWithGoogle(acct: GoogleSignInAccount) {
        val credential = GoogleAuthProvider.getCredential(acct.idToken, null)
        auth.signInWithCredential(credential)
                .addOnCompleteListener(this) { task ->
                    if (task.isSuccessful) {
                        val user = auth.currentUser
                    } else {
                        Log.w("LOG", "signInWithCredential:failure", task.exception)
                    }
                }
    }

error:

Do you activate the support of at least 2 authentication providers on your firebase console like it's specified in the documentation?

Please check in Firebase Console => Authentication => Connection Mode and enable the connection method you needed.
