How do I embed a Media Gallery Playlist in a Canvas text-editing window?
Instructors and TAs can embed a Media Gallery Playlist in any Canvas text box, including in Announcements, Pages, Syllabus, Assignments, and Discussions.
Note: Students cannot embed a Media Gallery Playlist in a Canvas text box as they do not have permission to create a Media Gallery Playlist. Students can, however, embed any of the videos they upload to their My Media in a Canvas text-editing window.
