Save Chat - Java Script?

Hi, I am using Zoom with a free account for some months as participant of a language course, and saving the chat afterwards had never been a problem. But for the last two or three weeks I can't do that any more - could it be a problem with this JavaScript-topic (log4j) we're facing since December 11th? I'm not sure if we are allowed to post hyperlinks here, but more information can be seen on the bsi-website. But that's only a guess of mine, maybe it's a totally different thing with the chat... Thanks for helping, Christine
