How to set an app's icon in the dock on Linux? [Solved]

So apparently a valid .desktop file installed in ~/.local/share/applications/ or /usr/share/applications/ is what is needed to define a dock icon for a wxPython app in Ubuntu, for any future readers.

There’s one more important detail:

• The name of the .desktop file must match the name of the executable it links to. Otherwise the icon doesn’t show up.

In my example above I have a crystal.desktop file pointing to the crystal binary installed via pipx. If I rename the desktop file to something like net.dafoster.Crystal.desktop then the generic gear icon shows up in the dock rather than the proper app icon!
