I created a 'practice' video in canvas studio.  The video is currently 'unassigned" to any module in any of my courses and exists only in "my Library".  I have confirmed that I am able to make a video and I even uploaded it to Panopto to verify 'stuff".  Anyway, here's the situation:  I was successful at deleting the video from the Panopto site, but I cannot delete the video from the studio 'My Library".  How do I delete a video from "My library"?  I have tried dragging the file to recycle bin, toggling through the stop-light tabs on the video, and every mouse right-click/delete function known to science.  Please help!
