I don’t actually have a Mac to test on so I rented an m1 mini on the other side of the planet to test it. It’s a real pain but if I recall correctly it did run and the tray icon appeared, though I think it also shows up in the app bar.
It’s running .net6 with Avalonia for the GUI, doesn’t support encrypted SQLite. Might eat your neighbors homework.
