How can I fast-track my immigration process in Thailand with an online appointment for a Covid extension?

MTT Covid extension, UK passport/apec card.

Set my personal best time today, 24 mins in & out.

They asked for an online appointment confirmation & it seemed to fasttrack me to the immigration desk. There were 30 or so people waiting in the document check room who didnt seem to have made an appointment & were dripped through 1 by 1, but I would 100% make an online appointment.

Under Consideration until 4th Feb. Which is mildly annoying considering the location, but musnt grumble too much given the circumstances.

Got the 116 bus from Victory Monument, 22thb! & a cab back to BTS Lad Phrao 125thb.
