audience property
Audience is an opaque reference to the segment this campaign targets. It is stored and echoed but not yet handed to the executors — a channel targets through the provider account it runs under — so it is documentation for now. Absent when never set.
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? audience;
