Does a DTV visa require entry into Thailand within 90 days, or can one enter at any time within its 5-year validity?

The DTV (digital nomad visa) is valid for 5 years from the date of issuance, and the holder can enter Thailand at any time within that 5-year period. There is no requirement to arrive within 90 days as is common with other visa types—entry can be made at any point during the visa's validity.
