I do not understand the difference between courses and lessons. Impossible to make a menu link to a lesson. Why ?

Thank you for your patience.

You can know in more details about the course in the documentation link: https://www.joomshaper.com/documentation/joomla-extensions/sp-lms/all-about-the-course

And, when everything is in order (teachers, course categories, courses are created) we begin to create a lesson.
