We have a educational website and embed youtube videos. When an embedded video is paused, YouTube will display a menu with "More Videos" and it's not a good user experience. I looked at one of your videos (https://www.khanacademy.org/math/algebra-basics/basic-alg-foundations/alg-basics-negative-numbers/v/opposite-of-a-number?modal= 1) and it doesn't show "More Videos" when paused. May I know how to disable the "More Videos" feature?  I'm really grateful for that.

Best Regards.
