Add custom header oauth2

Questions

i am trying to pull some data from my bank and they offer an OAuth2 API.

however they require custom headers to be added on each request (and in the oauth2 setup).

i can’t complete the oauth2 setup because it replies unknown client id etc (because i didn’t set the client id header i presume).

didn’t manage to find a way to set anything like that on the OAuth2 API credentials setup. is there a way to do this? if not can you please point me to a workaround?

    X-Request-ID: a client generated guid to uniquely identify each call
    X-IBM-Client-Id: myapp001.ClientId

The only workaround for now would be to implement the OAuth2 logic manually with HTTP Request Nodes.
