Passing the access token as SessionID for Adobe Workfront REST API invoke

Summary:

Adobe Workfront API V21 requires the access token in a custom header named SessionID, not Authorization: Bearer

Adobe Workfront API V21 uses OAuth Client Credentials using JWT Client Assertion

I successfully created the REST Connection with "OAuth Client Credentials using JWT Client Assertion" security policy. Test passes.

The problem is the REST adapter will put he access token in Authorization: Bearer header.

Is there a way to tell OIC Integration Invoke Action to pass the access token in a header named SessionID?

PS - thanks Adobe developers for not following standards, ugh!
