DJI V2 Goggles video HUD overlay in Mission Planner

I would really like the video HUD overlay of a DJI FPV goggle in Mission Planner, but I don’t have any idea how to start, did antyone try this already?

I already installed DJIVideoOut and I have the DJI video on the same computer as Mission Planner, but I cannot selct this as a video device in mission planner, is there a way to do this?
