Can I extend my 90-day visa exemption in Thailand or switch to another type of visa after three months?

The user is inquiring about their options after entering Thailand on a 90-day visa exemption with an Argentine passport. They want to know if they can apply for a 30-day extension, a 60-day COVID extension, or switch to another visa type to stay longer. Responses indicate that there is no 30-day extension available for those entering under the visa exemption, and the 60-day COVID extension program is ending soon. However, switching to another visa type may be possible and should be explored within the three-month period.
