I am reading the Thailand Pass FAQ.
"5. I have previously been infected with COVID-19; can I travel to Thailand?
- Yes. Those previously infected with COVID-19 are considered fully vaccinated if they have
received a single dose of COVID-19 vaccine within 3 months after their recovery. In this
case, your proof or medical record of COVID-19 recovery must be submitted alongside your
single-dose vaccination certificate.
- If you have been fully vaccinated before contracting COVID-19, you are still considered to
be fully vaccinated.
- Those who have recovered from COVID-19 within 3 months before travelling to Thailand
must present a valid COVID-19 recovery form or medical certificate certifying that they have
recovered from COVID-19 or are asymptomatic in case their COVID-19 RT-PCR test shows a
positive result."
Seems like your challenge is to get a medical facility to sign off that you are recovered and a paper in line with what is expected.

I would recommend seeking advice from Thai Embassy where you depart and discuss this with your planned airline.
