Show icon in system tray

Hi,

I’m using Ubuntu 18.04 with Gnome desktop. Gnome does not support a system tray anymore, but I want to start Cryptomator in background (hidden mode). Does anyone see a solution to do so?

I already tried https://extensions.gnome.org/extension/615/appindicator-support/ and https://extensions.gnome.org/extension/1503/tray-icons/ , but only the last one worked a bit. There was displayed a black icon instead of the original one.

Does anyone use a Gnome extension that works? Or is there any other solution?

Thank you!
