* Specify whether an ID token should be acquired for hints, if available for the selected credential identifier.
* This is enabled by default; disable this if your app does not use ID tokens as part of authentication to decrease latency in retrieving credentials and credential hints.
* Enables returning {@link Credential} hints where the identifier is a phone number, intended for use with a password chosen by the user or SMS verification.
* Specify the server client ID for the backend associated with this app.
* If a Google ID token can be generated for a retrieved credential or hint, and the specified server client ID is correctly configured to be associated with the app, then it will be used as the audience of the generated token.
* If a null value is specified, the default audience will be used for the generated ID token.
