SelectedCountryNameCode Length

Is there any option to get the selected country code length as 3 chars ? Example for **India -> IND not as IN**

Start by reading the library's country-selection API and how the selected country's code is represented. Confirm whether a three-character code such as IND can be exposed alongside the existing two-character code, and consider the expected behavior for selected countries. Done means the requested three-character country code can be retrieved reliably.
