What are the requirements for obtaining a Thai Digital Nomad Visa and the Soft Power Visa?

Please correct me if this is completely wrong or just a puerile question, but do I get it right that, no matter via which Embassy you apply, it's likely that DTVisa applications for Digital Nomads where the applicant is forcing to keep doing his/her remote job abroad are supposed to hand work contracts/arrangements, portfolios (or just one of the last three ones) AND documents that show monthly income (based on their profession) while DTV applications of people who are willing to participate in Thai Soft Powers (like cooking class or Muay Thai course) are "only" supposed to include a bank account that is well balanced (B 500,000, for the past three months at least) and the confirmation of that particular Thai soft power/cultural course?

Sometimes it seems unpredictable which argumentation is received well by the Thai embassies.

Is it counterproductive to include proof of a remote job arrangement of your company (thus, a monthly income) when you are determined to "only" participate in a Muay Thai course? Some Embassies can be very erratic when it comes to the constellation of your application's legend 🙄

Thanks so much for your attention!
