I am creating a mandatory course in Rise. It has 2 sections and 15 lessons in all. We have to make sure all 15 chapters are viewed and understood. How can we control the navigation to make sure the learners do not skip the lessons and every single one is viewed. Currently, I also have the table of content. This gives the flexibility to move around freely. Will it add value to take that off? If yes, is it possible to hide or delete table of contents? The goal is not make the table of contents not clickable unless the lesson before is complete.
