Antigen Test for Turkey (Not fully vaccinated 12 year old)

tompiper

My daughter has only had one jab (only just turned 12) so is considered to be an unvaccinated adult.
I understand that she will need a negative lateral flow (antigen) result no more that 48 hours before but I am not clear on which  one of the available options I need to take.
There are the ones where you just have to send a photo and then this is validated by the test provider. Or there is a "supervised test" which is obviously more expensive. 
I cannot find a definitive answer from the Turkish Embassy website as to whether the first option is acceptable. It just says a negative antigen test within the last 48 hours.
Has anybody any recent experience?

Thanks
