What is the process for obtaining a Soft Power Visa in Thailand and what does 'employment prohibited' mean?

Soft Power HCMC update

I know a lot of people doing applying through HCMC for soft power visa have had some trouble, so I'll post my update.

After I submitted my initial application with all of my documents, I got a request for further documentation 2 days later. They were asking for proof of income.

I then submitted a letter explaining that my application was for soft power activities (muay thai training), and that I was unemployed. I confirmed that I will not be working in Thailand. I also included 6 months from statements from my brokerage account and my Neo bank account, to explain that this is where the recent lump sum of money into my bank account came from, and also this is where I would gather funds from to pay for any other large unexpected expenses.

I then got approval for my visa 2 days later, and now I have the 5 year DTV. The only thing is that they made a remark on the acceptance saying employment prohibited ; I'm not sure if it's normal or important, but I don't think it will matter anyways since I don't plan to be employed in Thailand
