How long must 2 million baht stay in a company's current account for a visa and work permit application in Thailand?

Set up a company 3 months ago. Does anyone know how long the 2 million baht should stay in the business current account for? A set time or it has to still be in there during initial visa and wp applications, extensions, renewals.

And what percentage/amount of it is ok to withdraw? (to put for example into a personal, less taxed and better rate savings account)

Or if 2 million has to stay in the business account is it ok for the majority of that to be put it into a business saving account. Any info appreciated
