Automatic attendance in v3.0.0

Since version 1, I was thinking about how can I make this entire process automatic, but this was not something easy.

There are a number of ways into achieving automation, such as monitoring DOM changes, listening for API updates, and others.

Finally, after days of reverse engineering the source code of Google Meet, I managed to consistently track the events of people joining and leaving the call. I quickly updated the dashboard to reflect the latest data additions. This was big.
