username property
Username is the validated principal's user ID — the opaque gateway id, which is what argocd's UI renders as the signed-in user here — or "admin" when the principal carries none. Absent when anonymous.
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? username;
