Browser extension to record

It would be nice to be able to record the instructional videos to generate notes/summaries. Right now, you can record it with just using the system microphone and letting it play out loud through the speakers. If there was an extension on the browser to directly record the audio of a video, this would allow users to have headphones phone to listen to the lecture. The extension should have the capability of connecting to the meeting apps like MS Team, WebEx, Zoom, Google Meet, etc, since many people have one but not the other. For example, my company uses MS Teams, but some costumers have WebEx or Zoom. When I join using the browser because I hardly use the others, I don't want to install those apps. I want the capability of joining through the browser and have Wave record it and not have to use the computer's mic and speakers to record the session.
