I find this feature has the right amount of discoverability as-is. Considering it is an advanced feature that should be used with care it make sense to use an icon-only button in my opinion (and that's also why I initially designed it this way).

We might want to reconsider the design anyway with https://progress.opensuse.org/issues/166556. Maybe you want to incorporate that into your ideas?
