Well, thanks to a user on the SketchUp Forum, I have found a way to download Box's YouTube videos and add them to my folder. Since they are mp4 videos they can then be played via Media Player (which launches in a separate window and allows you to pause them).
There is an extension for Microsoft Edge called Internet Download Manager. Here is a link to a video that will tell you how to install it in Microsoft Edge: How to install Internet Download Manager
