3rd Party plugin un-installer didn't remove their button from toolbar - How can I manually remove?

(UE5.5)
A while back I un-installed several demo plug-ins from UE and just noticed that one of them (I don’t remember the company) never removed their button from the UE toolbar.

Is there someplace in UE where I can manually remove this myself?

Solved:
I was able to find mention of an original name for the plugin and discovered that their un-install .exe didn’t remove that plugin folder. Once I removed the folder manually, the icon no longer displays in my UE Toolbar.
