Can I apply for a Digital Nomad Visa (DTV) in Thailand without payslips or invoices from my freelance clients?

Soo. I am a freelancer, but I don’t get “payslips” or invoices for my local clients(I’m from India). I just met the clients I have locally in person and they told me what they would want every month, and I provide them what they want every month for which they transfer me the payment every single month. I’ve got the same fixed payment from these clients every single month for the last 2 years, but I don’t receive any payslips or invoices for the same.

I have more than 2 million THB in my savings account(way more than the 500k required for DTV) and I also have freelance clients through fiverr and have an Etsy shop. But the fiverr and etsy shop aren’t something that give me a fixed monthly income. it’s on and off and some months I get a lot of clients and some months are flat af. Do you think I can apply for a DTV based on my local(2 clients) that I have even though I can prove the payment through showing the payment in my bank account and can present my tax statements, but don’t have payslips or invoices for the same?
