@Deprecated methods on AuthUI.IdpConfig.Builder, AuthUI.IdpConfig,
IdpResponse, and AuthUI.SignInIntentBuilder. Most of the deprecated methods have to do
with configuring the FirebaseUI sign-in Intent and the replacements can be seen in the README.firebase-firestore library version 16.0.0. The primary
breaking change is the removal of QueryListenOptions, which has been replaced by the
MetadataChanges enum. See the firebase release notes for more information.
