Privacy for multiple organisations

hello, I am trying to set up Opigno 2 LMS as a learning platform for teachers. The idea is to allow teachers from multiple schools to access the same lessons and resources but keep separate classes and students. I cannot see any way of stopping every teacher/student on the site from being able to see every class available and I cant see a way to stop Teachers from different schools from having access to every student (i.e. they could add a student from a different school to one of their own classes). is it possible to do this in opigno 2.0? best regard !
