Hi, I'm Luis a Xbox user just like you. Thanks for reaching out us here. Linking accounts won't give you access to games bought on another platform.

You would need to buy the xbox version of the desired games if you want to play them through the Xbox app

It doesn't show up on the Microsoft Store library, but does show up on the Xbox app

UWPHook is a simple utility created by coder Brian Lima. Using this app, you can effectively "reveal" UWP games to Steam's framework, allowing you to add them to your library like any other executable file. You can download the UWPHook installer from Lima's GitHub page.

Once you've installed UWPHook, adding UWP games to your Steam library is a snap.

Open the UWPHook app.

Click the refresh button on the top-right of the window to get a list of all current UWP apps installed on your computer.

Scroll through the list to find any Microsoft Store/PC Game Pass games you have installed, and click the checkbox next to the ones you'd like to add to Steam.

When you've selected your games, click the "Export selected apps to Steam" button on the bottom right.

After a moment, a notification will pop up informing you that the games have been added successfully.

Restart the Steam client.

When you open Steam, the games should appear in your library.

Once a game has been added to your Steam library, you can launch it from Steam the same way as regular Steam apps. Even if the game was downloaded via a PC Game Pass subscription, you likely won't need the Xbox app running while you play it (though some may require it).

If you're on console it would be in your library in Games and Apps as ready to install.

On PC, it would be in your library in the Microsoft Store app or Xbox app.

You should also just be able to look the game up in the store and it'll show that you already on it and can install it from there.
