An AuthTokenContext object can be passed to getToken to provide additional information during token generation.

public interface AuthTokenFactory

Provides authorization tokens for accessing the provider's service account on Fleet Engine via gRPC. The factory ensures that there is always a valid access token available. The access token should have a remaining minimum lifetime of at least 5 minutes to allow for requests to complete. That means that the access token factory must automatically renew expiring tokens. It should also minimize the number of token refreshes by re-using a token until its lifetime nears its end.
