Registering coursepress post type as public


I had a discussion with this plugin author about his plugin not appearing on site wide (specifically the sidebar isn't displayed inside courses).

After diagnosing the issue he told me: "Site wide works. But as for the post type issue, solution is that CoursePress registers post type as public (and it is public, I am not sure why they set it as private in the first place)."

Is it possible to make this post type public?
