minimwatch unable to create tray icon

[Ronnhedh]

When installing ARM 64bit MinimServer & MinimWatch on Raspberry, the error message "MinimWatch unable to create tray icon".

Th only guideline I found is this:

"Installing MinimWatch 2 on Linux
If you're using ..... Debian 10 or later) and you want to use MinimWatch desktop integration, install the GNOME Shell extension TopIconsFix before installing MinimWatch. If you don't install TopIconsFix, you will see a message "unable to create tray icon" when you launch MinimWatch."

Searching for TopIconsFix, I found something as a Gnome shell extension which I tried to wownliad without success.

Is there a more trivial workaround on this, I believe, common issue?

B.T.W. the ARM hard float 32 -bit MinimServer & MinimWatch works flawlessly on a day to day basis. Many thanks!
