We are using heroic enterprise cloud. We are not seeing options to add configuration related to IAP mentioned here for Google and Apple. Basically shared_password for apple and client_email and private_key for Google are missing in configuration tab.
later in developer console we can see apple.shared_password, google.client_email and google.private_key are populating as empty.
