Meta settings box in the frontend

Hi there.
I’m using this plugin with the Masterstudy LMS plugin which has a frontend course creator.

I want to restrict access to my course only to some groups, using the frontend editor.
Actually I have to create a course from the backend, set the Group access, save, go the frontend editor and then create the course.

I want to show the Groups settings meta box in the frontend editor, even editing the PHP pages.
Is there something I can do?
I’m reading the code but I’m not finding something useful… thanks!
