Can I apply for another 30-day extension after a visa on arrival in Thailand?

The user entered Thailand on a visa on arrival and extended it for 30 days, followed by a 60-day COVID extension. They are inquiring about the possibility of applying for another 30-day extension before their flight back to the UK in June. The responses indicate that a second 30-day extension is not possible; however, the user is advised to apply for another 60-day extension based on being unable to travel.
