[Digital Nomad Visa] Streamline employment verification for contractors

Hello to all my peeps who've successfully applied for the Thai DTV (digital Thailand visa)! I've just been asked to provide a follow-up doc to my application package * **Other request documents:** Employment Verification Letter from the employer serves as proof of employment. The letter must include the employee's Full Name, position, duration of employment, and be signed by an authorized person, such as someone from the HR department or a manager I work for an established ai data training company. We are "contractors" paid hourly, technically 1099 if we meet the threshold. We never received an official employee agreement (since we aren't full-time employees) nor did we sign any contracts/official paperwork prior to working. I only ever received a "welcome to the platform" email from a no-reply email, but the domain is company official. Does anyone know the purpose of WHY they need this, even though I meet the requirements of ongoing work, legitimate end-to-end payouts, bank savings > threshold? My package already had screenshots of platform payouts, PayPal transaction histories, and bank statements proving the end-to-end payment chain for the last 3 months. I also included screenshots of the platform itself, showing proof of available work. I applied through the Washington embassy. My 3 months of bank statements prove I'm over the threshold. I thought my package would be solid, but I'm confused (and worried) why they need this employee verification form - I don't think my company will provide one, since we aren't employees to begin with - just contractors. I reached out anyway, but my hopes aren't high - any suggestions on how to proceed would be huge, as I leave in about 2 weeks. I'm thinking of providing screenshots of my emails showing the "welcome aboard" email, screenshots of dozens of emails I've received from them proving I'm actually working there, etc - if I knew WHY they were asking for this doc, I could really narrow my response. Any help is REALLY appreciated - thanks in advance!
