What permission sets ''Superuser'' for lock posts?

Superuser is designed for network wide (multisite)
I'm using Lock Posts on a single site, meaning Admin is the superuser.
I found adding another Admin user means they can Lock & Unlock posts,
but the purpose of this plugin is to set site pages to be editable on a set by set basis.

I'm aware that removing permissions from a custom role can accomplish this,
so what permission is the one to remove so that a Admin can
edit site pages, excluding ones set to Lock by ''Lock Posts'' plugin?

Also thank you for any replies :smiley: I appreciate the support of the amazing WPMU team.
