        VerifyNotificationChannel() on a different channel with
        an equivalent identity in the same or in a different
        project. This makes it possible to copy a channel
        between projects without requiring manual reverification

        typically return a much longer, websafe base 64 encoded
        string that has a longer expiration time.
