Old AppleTVs don't have an App Store.

I can’t get YouTube TV to add to kitchen TV. This is the older Apple TV and I can’t tell how to “add” Apple TV.

I seem to recall the older AppleTV you are now using in the kitchen may be too old to have access to the App Store. Back in the old days (appletv version 1) only a few applications were allowed onto the older devices. Mostly big apps of the day. Ie: Netflix, ESPN, Disney+, etc…. However as streaming evolved, the older appletvs software development was abandoned as the newer applications like Peacock, Paramount, YoutubeTV, SlingTV, etc… need more horsepower than the older version appletvs could provide.

In short, the kitchen AppleTV is very likely too old to run apps you’d like to have.
