What documents are needed for applying under the digital nomad/freelancer visa category in Thailand?

I'm planning to apply under the digtial nomad / freelancer category and was going to submit the following documents. I'm a programmer.

Are there any other documents I should include?

Thanks!

- Proof of employment letter (I work for myself and have a company but made one and signed it since I heard that's what people are doing

- Articles of incorporation (shoing I own the company)

- Letter stating I can work from anywhere, including Thailand, and have no business in Thailand

- 3 Months bank statments

- Pics of all passport pages

- Taiwan Immigartion Entry/Exit data form

- CV + Portfolio

Edit:

I was also submitted the following

- cover letter

- 1 client invoice with proof of payment with a bank statement (about 10k USD)

In the interview I was asked why I wanted to go to Thailand, why I didn't just get a multi entry visa, and about what I do for work and who my clients are.
