Hit Windows+R, type "shell:appsfolder", find the app there, right click -> create shortcut.

I immediately found a workaround for Unity3D. Create a .bat file with the contents: cd "C:\Users\username\AppData\Local\Microsoft\WindowsApps\" start AffinityPhoto2.exe %* and set the bat file as your external tool. Not really ideal, though.

This change made the application almost unusable for my daily workflow. Since the path the application is installed to is locked away by Windows, even to administrator accounts, a lot of application can't launch it externally. E.g. Unity3D will not allow me to mark Affinity as my external image editor, which means I can no longer open images directly from Unity3D, which is how I use Affinity 99% of the time. The Stream Deck also can't launch the application anymore. You have to find a hidden folder in windows (not the actual application path), find the app and create a shortcut, which Windows will not allow and ask to place to place it on the desktop, which you can then link to. That workaround took me a while to figure out, considering what a simple task it should've been.
