Duplicate icon in notification bar

[fmmarzoa]

Problem:

In Ubuntu 18.04 at least, if you close the whatsdesktop window and then launch it again from the dock, it will open a new instance instead of opening a new window for the one that's already running, as a result you'll end up with two whatsdesktop icons in the top notification bar (the tray). Moreover, the second instance will show the qr code to join Whatsapp again.

Expected behaviour:

Whatsdesktop should prevent multiple instances from being run concurrently.

How did you even get this icon? It never appeared for me, so I simply presumued the app wasn't compatible.
