Doesn't detect flatpak tidal-hifi players.

[aljustiet]

I have tidal-hifi installed through flatpak, and when I play audio and check with playerctl --list-all, it doesn't its player.
How do I make this flatpak app work with playerctl?

Looks like the tidal-hifi Flatpak build was fixed in March, and should work now. The issue was on the packaging end. (Mastermindzh/tidal-hifi#540)
