How to hide submenu on WPMU membership site

I’m using the wpmudev membership plugin.

I’d like to hide the submenu on a WPMU membership site for free members. In other words, I only want premium members to see the sub-menu while the top-level menu displays for everyone else.

The top level or main menu contains Home, About, Products, Contact tabs/links. Only the Products link contain a submenu of services that should only be viewable by premium members.

I wonder if someone can share a css code or php code or other hack I can use to hid the submenu for the Products tab?

Or is there a way in WP admin to permit only premium users to view sub-menu? Can the admin control who sees the sub-menu? I’m reading https://www.ads-software.com/support/topic/how-to-hide-users-login-log-sub-menu-for-sub-sites-in-multisite?replies=4
