Can a foreign bank account be used to demonstrate financial requirements for a Thai retirement visa application?

General (Covid unrelated) question: If one wishes to apply for his first and initial "retirement" visa (non-o/non-oa) with a Thai embassy abroad and is required to demonstrate compliance with relevant financial requirements, would he need to show that he has sufficient funds (Thai Baht) in a "Thai bank account" or could it also be an equivalent amount foreign currency in an account with a bank which is located outside Thailand?
