Info Tip when hovering over folder in Folder Tree

My goal is to get an Info Tip that shows me which labels are added to a folder when I hover over a folder in the Folder Tree.
I already edited a few File and Folder Types and that works when I am IN a folder and hover over a subfolder, but when hovering over a folder in the Folder Tree, nothing happens (only the name will pop up when the name is too long to show).

The answer that was given in this similar issue from 2 years ago is not working for the folder tree. Or am I missing something?

Hopefully someone can help me,

The folder tree doesn't display Info Tips at all. It will only show a tooltip with the full item name if you hover over an item that is too wide to be fully displayed.
