How to get rid of .hidden superuser dolphin from Menu

Hi, I have no idea how a ‘.hidden superuser dolphin’ ended up in my start menu, but because it’s shown as .hidden, it’s not shown in the menu editor. Is there any way to get rid of it? When I right click on it, it simply starts KDESU. Thanks.

If you go to menu editor - settings - config - Misc
enable show hidden

can you then delete using the editor?

Thanks a lot, it worked!
