If a video is embedded for standard viewing, then this CAN be done in the page content on the content portal. 

If an embedded video requires the Video Progression application (meaning the video needs to be watched to the end before the learner can move on), this must be handled differently:

• This entails putting [ld_video] into the area where you want the video to show.
• Within the lesson on the receiving LMS portal, you will need to add the link to the video.

The reason for this is that Video Progression is a LearnDash function, so there is no way to apply it to a video embedded in a content page in Elementor.
