Keyboard shortcut for a script

Need some help with setting up a Keyboard shortcut.

I have this Origin Move to Selected script, that has an bl_idname (which should make it accessible) and I’m trying to keymap it to Ctrl+Shift+C.

I also disabled all conflicts, but the key combo is not working. Any help?

It’s working when invoked from the Spacebar search menu, where it is named as Object: Origin Move to Selected.
