I also spent a long time looking for an extension to record meetings in Google Meet and I can share my experience. For me, the most important thing was that the extension was easy to use, did not require complex settings and, of course, supported all the features it promised. As for functionality, the extension I chose records both audio and video, and with good quality. You can record not only your meeting, but also joint presentations, including screen sharing. All recordings are automatically saved to Google Drive, and you can access them at any time, which makes the process of storing recordings convenient and safe.
