Where to see ‘Now playing’ on apple tv via Airplay?

I like to stream music from the Youtube Music app on my iphone to my Apple tv. And I used to be able to see what music and artist I’m listening to via Airplay.

But now, when I hold the button to see the ‘switch user’ menu, I can see a tiny block that says what song is playing. But when I click on it to (hopefully) get it in full screen, it does nothing.

When I click on the Airplay button, I see something that looks more like a ‘Now Playing’ screen, but that disappears after 30 seconds or so.

Someone said they found a workaround by going to the Apple Music app on the tv and go to ‘Now Playing’, but then it only shows an empty artwork and ‘NOT Playing’.

I’m guessing all of this has to do with me not using Apple Music, but since I WAS able to see a ‘Now Playing’ screen whenever I was streaming anything to the Apple Tv, I was just wondering if there’s a way to bring it back!
