Since Microsoft seems to be a bit unresponsive to implement automatic recording of meetings, I wrote a Keyboard Maestro macro that will do the trick of opening a class meeting and automatically start recording.
I hope this can help fellow teachers to diminish their cognitive burden and concentrate on actual teaching.
Hello! The macro is simulating keystrokes and clicking on images (it looks for the camera icon to start a meeting, for example). To start a class, I go to the appropriate channel (usually the "General" channel in a team corresponding to a class) and start the macro with CTRL+K M.
It's been working fine and solved the problem of forgetting to start recording at the beginning of a class.
