Add a command line option to start the Proton Drive Windows app minimized to the system tray, with no window popping up after starting, E.g. --background or --start-in-tray.

Equivalent of starting the Proton Drive app on Windows and immediately closing the window, so that it sits in the system tray without having a window opened at the desktop.

The command "C:\Users\MyUsername\AppData\Local\Programs\Proton\Drive\ProtonDrive.exe --start-in-tray" could then be used to start the app in the background from scripts.
