You can add them as shortcuts. UWP need a tool to set them up in steam, but you can do them too.
They’ll still need to open the other launchers to run, but it’s about as close to seamless as you’ll get. You can make Windows log in automatically, not lock when it sleeps, and launch to steam big picture mode. It might take a search or two to set up, but after it’s (minus windows being windows) relatively out of your way.
You can do the same with Linux, but you lose anticheat games and setting up other launchers is more work.
Unless it’s changed in the last year or so, Windows store stuff doesn’t show up, because it’s not a normal executable. You needed UWP hook to import them to Steam.
