Adding Categories/Boards Dynamically

[DO MGBK]

Hi,
I am new to NodeBB. I want to use NodeBB for the school, every class will have its own discussion boards, the discussion board can only be accessed by the students in the class and moderated by the classroom teachers. How do I create the board dynamically and restrict access for a certain group of people? I don't need NodeBB's user management system as our application has already authenticated users, so this is assuming students and teachers are already logged in with JWT token stored in the cookie.

Your help is appreciated!
