CreateReportingDataAnnotation, GetReportingDataAnnotation, ListReportingDataAnnotations, UpdateReportingDataAnnotation and DeleteReportingDataAnnotation methods for managing ReportingDataAnnotation resources with the Admin API v1alpha.Annotations allow users to add notes directly to Google Analytics reports, making it easier to record events, explain changes in data, or highlight key observations for yourself and your team.
