What type of bank statement should I request for a Vietnam workation visa application?

The user is seeking advice on how to request a specific type of bank statement for their workation visa application in Vietnam, noting their bank is in the U.S. They are unsure of the requirements for the account balance and wonder whether a three-month bank statement is necessary or if an account balance alone will suffice. A commenter suggests that it may be better to ask for a six-month statement.
