How to mark lab complete

Hi this is my first time taking a course here, and have some basic questions. As i navigate the course, there are videos and quizes and labs. When I complete videos and quizzes they are marked complete with a purple check. However, it is not clear to me how to “complete” a Lab. When I click the link, it opens in Jupyter notebooks., there I do the exercises and run the code to the “Conclusion” section. Then what? Save and close? My lab does not get checked “complete” in the course navigation. Can someone explain what is the process?

Thanks,

Which course are you attending, and on what platform (DL.AI Learning Platform, or on Coursera)?

Are you asking about an optional lab, or a graded assignment lab?
