Where is home kit app in my new apple tv 4k128

There is no such thing as a HomeKit app for Apple TV.

The Home app is available for iPhone and iPad (and Mac and Apple Watch), but Apple TV doesn’t have this HomeKit management app. The Apple TV box can do its home hub functionality, while the Home app is on different devices. That is how HomeKit is designed to be.

Correct, but still sucks ;-)

Have to many Apple products and really like to know which HomePods OR AppleTVs are actually Hub.

Deleted multiple gear from Home app and turned off an multiple Apple TVs to try to steer it to certain one!

No clue, FYI with latest updates nothing works anyway :-(
