What is the process for obtaining a Covid extension for a tourist visa in Thailand?

This group has been extremely helpful, I wanted to give an update on the covid extension experience today - My daughter has just been granted her second Covid extension. Process extremely smooth at Chaeng Wattana, in and out in 30 mins. She arrived in November 2021 on a 60 day tourist visa, got 30 day extension and then a 60 day covid extension until 22 March. Today’s extension was added on to the end of her previous covid extension (even though she is applying almost a month in advance), taking her to 21 May 2022. The IO also did the 30 report at the same time. Great service.
