[Bug Report] Tray icon stopped indicating unread messages + monochrome option

[Sadi58]

Describe the bug
Although it consumes about 30% less memory than whatsie and whatsapp-for-linux, which is an advantage for WALC, I no longer prefer using it after it stopped indicating that there are a number of unread messages via the the system tray icon some time ago - although I can hear a notification sound, and a notification message every time a new message is received in the background. The lack of the notification in the system tray constitutes a problem especially if, for instance, you receive messages when you're away from your computer for a while.
I would very much like to start using WALC again if this issue can be solved.
There's also a minor problem regarding the color of the tray icon:
It would be very nice to be able to use a monochrome tray icon with light and dark versions consistent with the global theme.

WALC Installation Type: AppImage
