assignee property
Assignee is who holds the work — an IAM username, or the login of the FIRST assignee when a forge issue has several. Absent when nobody holds it, which is exactly the state a claim needs.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? assignee;
