Do I need to book flights and a hotel before applying for a Thai TR visa in the UK?

The applicant is seeking clarification on whether flight and hotel bookings are necessary before applying for a TR visa in the UK. The embassy indicated that these bookings are not required during the application process. However, anecdotal evidence from others suggests that the visa team may request flight confirmations after submission. Some commenters recommend uploading screenshots of unbooked flights as a contingency. A suggestion was also made to apply for the TR visa first, potentially handling additional documentation later.
