Description

Thanks for such great extension and it helps a lot with API.
For some reason, We are facing error CORS Preflight did not Succeed.
Looks like the issue we have is that the preflight request is returning 400 from server (server to which we call don’t implement cors). I suppose they expect the api is server to server.

Is there a way to setup something in Extension to emulate server to server call?
