Attaching VideoMaterial to DockingRegion

I have a VideoMaterial inside a RealityView and want to attach this to a DockingRegion inside an immersive environment.

It appears that adding the VideoMaterial entity as a child of the docking region somewhat works, but there are no lighting effects (specular, diffuse) from the playing video.

So essentially, how can you add a VideoMaterial to a DockingRegion and achieve the same reflections/behavior as using AVPlayerViewController. The latter is not an option as I need custom controls.
