The list displays the course object that you have in your course.
In my example, I created a course page course object and embedded a video in it. I named the course page course object “One hour video,” but it can be named whatever you want. But the name doesn’t matter. Just select the course object that contains the video.
As an aside, it’s a best practice to give your course object descriptive names. It makes them easier to identify later. I recommend that when you add the course object you then immediately click “settings” and give it a name.
Let me know if you have any further questions.
