Please block it so that only the “super administrator” can have access

Hello, your plugin helps a lot, but I feel like it hasn’t been tested for Multisites, right?

Maybe it’s not even the goal, but I believe a small script can solve what I’m looking for.

I need to solidly add an option so that, for example, only the super administrator has access to the plugin. And it may only be possible to access the plugin through the toolbar on the Network Top Panel, and cannot be accessed directly by each site.

Thank you for your attention
