Mebership website for visiting certain pages


I would like to build a website in which authorized users can only view certain pages.
To do this, I first thought of a Membership plug-in as WP members. However, this usually determines a certain level, where a higher-level user can also visit other pages. So, ie, you can view different pages with a large group. Often this is used for paying visitors on a number of courses or video shows.
However, for this project, it is necessary that 1 group of users can only visit a particular set of pages created specifically for them. And not the pages belonging to another group of users. The number of (groups of) users can expire to dozens.

Does anyone know a good plug-in for this?
Thank you very much for anyone who wants to respond to this!
