I already did such a submit. Read only CRM APIs are not suficient for my requirements. I’m currently storing the client secret securely, so I have no issue moving forward. But if there was an option available that wouldn’t require this, it would be prefered, so we could facilate an easier configuration at our side.

I’m keeping an eye on the progress on this request.
