Creating an "Admin" level with some visibility for plug-ins, but not Membership visibility

Hi there! I have a series of sites that use a form (Gravity Forms plug-in). The GF plug-in requires Admin level for visbility, yet the users don't need to be super-admins to access that. I need to be able to create a restricted admin that allows me to set the user as an admin, initially, then to add them to a visibilty group that will allow them to see the gravity forms plug in, but not themembership, WPMU, and other tools/etc. Any suggestions? If I set them to admin, then they automatically have the "membership admin" visibility.

Running current WP install, Divi theme, on WPEngine.

Thanks!
