How does UWPHook actually work?

Hi!

I couldn't find any documentation on this, and was curious. What / how does UWPHook actually do what it does from a technical perspective? What's the piece that it's automating that actually allows UWP's to get added to Steam, that doesn't happen when you manually try?

The way it works on the steam libary part is creating a non steam game shortcut with UWPHook.exe and with a launch argument of the UWP app's ID (listable by running Get-AppxPackage –AllUsers | Select Name, PackageFullName in PowerShell). Then to get the Icon and art, it uses the SteamGridDB API.
