How to Configure REST Adapter OAuth Security Policy for Custom Header

Summary:

I'm able to successfully run a Curl command line and Postman Gui to retrieve an access token, but unable to convert them to a working OIC REST connection that requires custom header includes content-type and x-company over an on premise Connectivity Agent. I've opened an SR but not making progress.

Content (please ensure you mask any confidential information):

-X POST <server/api/token> -H "Content-Type" -H "X-Canopy-Company" -d "grant_type&username&password&client_id&client_secret"

Version (include the version you are using, if applicable):
