"show details" not working for snaps
With a desktop snap application open, you can go to "Show Details" and it will launch GNOME Software which expects an app id. The desktop id is being passed to Software and the result is Software displaying "Unable to find gnome-clocks_gnome-clocks.desktop".
This happens with any snap so attached is a gnome-mines snap (much smaller than gnome-clocks) for you to easily install ed and run:
$ snap install gnome-mines_3.34.0-dirty_amd64.snap --dangerous $ snap run gnome-mines
