Why no family sharing menu in library on macos Apple TV app?

I’ve just upgraded to macOS 12.1 and I thought that would bring the Apple TV app in line with iPadOS and iOS which both show a “Family Sharing” submenu item under Library, but that’s not the case. My daughter is still having to go into the Music App on her Mac and then “store” (which never made sense to begin with) to download content I’ve purchased. Weirdly the app help says there should be a menu item, but there isn’t: choices are Recently Added, Movies, TV Shows, Rentals, Home Videos and Downloaded.

Have Apple jumped the gun with their help page or is this menu item not available in the UK version of macOS some reason?

Before anyone gives me a link on setting up family sharing, I’ve had a share for 8 years now and settings are correct on my account. I’m just expecting cross-device for the App to look the same and I’m surprised that it doesn’t. Going into a store link in a different app to download family purchases on a Mac seems goofy as ****.
