How Can I Create an Emissive Video Material in RealityKit?

From this WWDC session video, apple suggests that any objects that appear to emit lights should shine color onto nearby objects.

But when I was trying to construct an cinema immersive space with videoMaterial and some other entities. I find that videoMaterial is not emissive and the nearby entity doesn't reflect any lights from the screen Entity where my videoMaterial is attached to.

What is the right way to achieve an effect similar to the TV app that is displayed in the video?
