Can Singaporeans successfully apply for DTV from the Thai embassy in Vietnam or other Southeast Asian countries?

The inquiry seeks information about whether Singaporeans have been successful in applying for a DTV (Digital Nomad Visa) at the Thai embassy in Vietnam, particularly in Ho Chi Minh City, or in other Southeast Asian countries. Additionally, the author is looking for a list of government-certified gyms in Bangkok that support DTV applications, noting that available options are often far from their location. A comment mentions that Tiger Eye, a service based in Bangkok, has provided documentation for successful DTV approvals.
