How to set up Super/Meta key to run main menu in LXQt spin?

Hi, everybody,

I downloaded Fedora 41 LXQt spin, which is great, except for Super/Meta key not working as the shortcut for main menu (as in other desktop environments).

How can I achieve this functionality?

I must say the ksuperkey program has not built since 8 years ago (copr repo). So I am reluctant to use it in this Fedora installation. But in Lubuntu forums they say just configuring the Super key will function as shortcut for main menu.

I just don’t get it. Please someone advice me.
