Do I need to hold 500k baht in my account for 3-6 months to apply for the Thai DTV as a digital nomad?

I'm looking at getting the Thai DTV and have some questions about the information that must be provided. Also, I'm not sure if my situation is a bit complicated so I'll detail it here as best I can.

I currently have a remote job and I have everything required to apply for the DTV as a digital nomad at the moment (a job contract and the equivalent of 500k baht). However, I keep reading that I will need to provide 3-6 months worth of bank statements with the application, which I can do. However, I haven't had the equivalent of 500k baht in my bank account prior to this month and only met this financial target at the end of February. Do applicants need to have held this amount for at least 3-6 months before applying, or do you just need to show that you have it at the time of application?

I'm also reading that different embassies are selective about this, and the information I'm getting online is very varied. I'm currently in SEA at the moment (Malaysia right now and I will likely go to Vietnam next).

Knowing this is important because I am in the midst of wanting to leave my job and start my own business, which I'm in the process of currently. I know I can also apply for the DTV with a registered business, which I'm hoping I'd be able to do later this year if I don't do it while still holding my current job. I suppose I figured that while I do still have my job, it'd be good to get the visa before I make the transition (since I currently do have a valid employment contract). It isn't my plan to stay in the job for another 3-6 months, as I am already speaking with potential clients.

Basically what I want to know is do I need to wait until I've held 500k baht in my account for at least 3-6 months, or would I be able to apply sooner? Also, I'm from Canada (if anyone is wondering about my nationality).
