I just think this isn't hard - if you want to stay here long term, go and get a proper visa. Op has exploited the system for two years, the party, as you describe it, if it isn't over, should be soon. The whole point of COVID extensions wasn't to allow people to stay here long term, it was people who couldn't get a flight home.
The COVID extensions were introduced for people who couldn't get a flight home which was a serious problem in 2020 - it was the generosity of a Thai government that they introduced it. It wasn't for people like you to stay here for two years without getting a proper visa.
That you've managed to exploit that, for seemingly two years - great that you have, but grow the f-up and go and get a proper visa.
