Is my documentation sufficient for applying for a Thailand Workation Visa as a Brazilian passport holder working remotely for a US company?

The user is preparing to apply for a workation visa to Thailand as a Brazilian passport holder, while working remotely for a US-based company. They have prepared a PDF with a recommendation letter allowing remote work from Thailand, company registration documents, and social media screenshots, but don't have a formal contract despite working for the company for three years. The comments suggest checking with an agency for guidance and emphasize the importance of the application location.
