Worldguard on-interact=deny disables breaking blocks

Hi, so I'm kinda new in moderating servers and I just got locked. I want certain groups made with luckperms to be able to interact with certain blocks, but when I use on-interact=deny in worldguard blacklist file, breaking blocks is also disabled. Is there a way to allow breaking blocks and also disable interacting with them. For example: a group 'blacksmith' is allowed to interact with anvils and other people not, but they can destroy anvils
