https://www.bluedothq.com/blog/record-a-google-meet-without-permission article describes the methods that have helped me the most. You can record a Google Meet meeting without asking for permission from participants using the Bluedot extension. This extension allows you to record video calls even if the participants have not given you permission. To use Bluedot, first install the extension in your browser. Once installed, open Google Meet and start your meeting. The Bluedot interface will display a recording option that you can activate at any time. It is important to note that the recording will take place in the background, and participants will not be notified that the recording has started.
