jacopo-j/WebXDownloader ? reverse-engineered prompt

Build me a browser extension for Webex meeting recordings that adds a download button right into the video player controls. When I open a recording, I want to be able to save the video as an mp4 with one click, and also get the direct HLS stream link if I need it.

I’d also like a simple way to export the meeting chat transcript, either as JSON or plain text, from the extension itself. It should work well in Firefox first, and if possible also be usable in Chrome, with Safari support if that’s realistic. Keep the experience simple and polished, like something I can install and use without much setup. If you need to check current browser extension docs or recording playback behavior online, feel free to do that.
