Remove Operator Command Shortcut Favorites

[KuwuroUsagi]

Simple Q hopefully a simple A.

Would like to remove some of these buttons pictured below so I don't accidentally click them while I'm playing and swinging my mouse around.
I see how to add more buttons, but not how to remove these seemingly "default" ones in the pack I'm using.

Press A on them? FTB Library buttons should be removable in 1.19 but not in 1.18, so check that

Not in 1.18

Thank you!
