Using OAuth2 with JWT authentication in an OutSystems environment

I am attempting to implement OAuth2 with JWT authentication in an OutSystems environment.  The best way (from an OutSystems standpoint) to do this is to create a sample request but I am finding it extremely difficult to create a sample request.  Although a "Connector" is available at the OutSystems code repository (Forge), it does not support OAuth2 with JWT authentication correctly.

The JWT.io Debugger will not generate encoded results for headers using RS256.  That generates a "Signature error" and fails to produce the results.  Basically, I'm left with trial and error.

May I suggest that Box produce its own OAuth2 with JWT debugger that supports what Box requires?
