I have tried embedding video using the parameters that remove controls and autoplay with looping. When I use YouTube, it still shows the play button. Any tricks to getting all controls to be invisible? I want it to autoplay and fill the frame wth no controls at all - similar to the appearance in this Cascade story map called Justice Deferred.
