serviceAccountId property
ServiceAccountID re-points (or, with "", clears) the IAM service account a scheduled run is billed as. Clearing it puts that spend back on the org.
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? serviceAccountId;
