What can HomeKit do with AppleTV?

What can HomeKit do with AppleTV? I’ve gone into the Home app, and while I can add my Apple TV 4K to a scene, the only option is to control music. I was hoping there would be other things I could do like get it out of sleep mode so if I run say a Movie Night scene it would wake the Apple TV. Or get it to open Apps on the Apple TV, set the volume etc.

I’ve tried tapping Apple TV as per the below screenshot, and I get haptic feedback but it doesn’t open any settings area; I just remain on the same screen.

I’ve done a web search for this and the results are all about setting up Apple TV as a home hub, which is not what I’m trying to do (I have a HomePod as my home hub).
