Deactivate Membership but still use Shortcodes?

Hi – I have purchased the Membership product. However, I’m not actually interested in most of what this plugin offers aside from being able to make some content visible on a page (via shortcodes). I thought this was an easy adjustment but I can’t seem to make it work. In other words, I don’t want to make my entire site private – I want it visible by default and then only certain content visible by certain members within a page.

Any help on this would be appreciated.
