+  //        hours to improve security unless business reasons mandate longer
+  //        expiration times. Shorter token lifetimes are generally more secure
+  //        since tokens that have been exfiltrated by attackers can be used for
+  //        a shorter time. you can configure the maximum lifetime of the
+  //        incoming token in the configuration of the mapper.
+  //        The resulting Google token will expire within an hour or at "exp",
+  //        whichever is earlier.
+  // - sub: JWT subject, identity asserted in the JWT.
+  // - aud: Configured in the mapper policy. By default the service account
+  //        email.
+  //
+  // Claims from the incoming token can be transferred into the output token
+  // accoding to the mapper configuration. The outgoing claim size is limited.
