What are the requirements for applying for a DTV visa through the Vienna Embassy, specifically for Muay Thai and cooking courses in Thailand?

Hi group :) Regarding DTV Soft-Activities Embassy Vienna: I hope there are people here who have applied for the DTV via eVisa from Austria through the Vienna Embassy and can help me. This embassy seems to be very strict. Muay Thai courses are only accepted from 4 months (less than 4 months are rejected), no seminars are accepted that serve to get to know Thai culture (but other embassies have approved them). Can anyone recommend a reliable and inexpensive Muay Thai boxing school or a cooking course in Chon Buri that has been approved? In other districts too, if they are cheaper. I just thought that it wouldn't hurt to actually go to Thai boxing (😄) every now and then :) Thank you very much for your help :)
