URemote controls with composure comp

I am doing a simple composure key with blackmagic input and using URemote for camera tracking, I’d like to be able to move the camera/set lens length etc once I pie and control with iPhone. Everything is displaying okay but I have the issue that when I setup the composite to output in the player viewport the touch controls on the URemote app seem to loose functionality and so does mouse keyboard or any game pad. Likewise the focus and focal length changes have no effect. What the best way to get continued functionality with the composure comp displayed, so I can still move/camera change settings? Many thanks
