How to restrict course catalog in LSO as per Employee Subgrou?

Hi Friends,

There is as requirement in my organization that course catalog in Learner Portal should be displayed as per employee sub-group.

For Ex, if Course A is dedicated to only group O1 employee and course B is dedicated to only O2 employee.

             Then Course - A in Learner Portal should be displayed for the employees whose Emp. Subgroup is O1.

             Similarly, course B in Learner Portal should be displayed to only employees whose Emp. Subgroup is O2.

Please guide me how to archive this requirement in LSO Lerner Portal.
