No panel icon in Gnome/Debian 13

Debian 13 is using Wayland rather than XWayland, so only a default icon is showing in the Gnome Shell panel. MakeMKV doesn't appear to have a WMClass so editing the .desktop file doesn't work.

You can't put any icons on Gnome's top panel.
You can drag & drop to Dash.

Sorry. I'm using an extension. D'oh!

But the same applies to the App/Window switcher. Only a default icon.
