Activating Plugins for Supporters

I think i must be missing something in regards to how mu-plugins are flagged as supporter only or site specific.

I totally get the regular plugins directory and the options for network and making them supporter only or not.

The mu-plugins like:






have intsalled them in mu-plugins and they work fine, BUT they are visible in every users dashboard and threw all my reading can not find where to enable or disable per site or for only supporters (like the themes)

Let me know what i am missing please, either i don’t understand something in how they work or am just completely overlooking it.
