Syncthing GTK does not appear in systray, remains running after clsoing window

As per the title, I'm running this on Sway, and I'm not getting a tray icon as I'd expect. Similarly, it's remaining running (with no way to access it).

Can I just disable the tray entirely maybe, so it just exits on window close? That'd be fine, though a working systray icon would be great too.

Thanks again for this! The Web UI is fine, but this is sure nice to have.
