The Cloud Shell back authorization channel uses serialized Javascript Protobuffers, preceded by
the message length and a new line character. However, the request message has no content, so a
token request consists of an empty JsPb, and its 2 character length prefix.
Returns a string representation of this credential, including request metadata and access
token.
Security Warning: The output of this method includes the request metadata which
contains the raw Bearer access token, and the raw access token value. Do not log this output in
production environments as it may expose sensitive credentials.
