Tray icon's "Quit" does not work

[yookoala]

Steps to Reproduce

1. Install with flatpak (not sure if the non-flatpak installation has the same issue or not)
2. Open an instance of youp. Link to Whatsapp as usual.
3. Right click the tray icon
4. Click "Close".

Expected Behaviour

All instance of Youp to be closed / quit.

Actual Behaviour

No instance of Youp is closed. The tray icon stay there.

Same here. Clicking "open App" actually closes the app entirely.
