In the edit menu of the groups you can set an icon for the group in the sidebar. This works when selecting a single word icon name, i.e. book or eye. It doesn't work when trying to set another name, i.e. with a dash, i.e. eye-check. The solution of this bug could be related to #7058.

Yep, it's a known problem and it's related ot that issue.
Depends on #7058

With the switch to the new Ikonly library, the issue is now resolved.
You can now use any icon from these here (MaterialDesignA....Z.java)
You have to use the "keys" .e.g EYE_CHECK

The idea is now to add an icon picker dialog to ease the selection of icons #6142
