Probably the simplest solution is to duplicate the handout and remove all of that, and show them the copy. Next up is copying the URL for the image and sending it in chat: [x](URL#.png) like: [x](<a href="https://s3.amazonaws.com/files.d20.io/images/269659873/PQI-LADkod_oxnyeSVNN9kA/original.png?1605278639591#.png" rel="nofollow">https://s3.amazonaws.com/files.d20.io/images/269659873/PQI-LADkod_oxnyeSVNN9kA/original.png?1605278639591#.png</a>) (the #.png is a "URL fragment" that lets the chat parser realize it's an image even though it ends in a number, just append it to the URL).
