-/**
- * Exports an audience list of users to a Google Sheet. After creating an
- * audience, the users are not immediately available for listing. First, a
- * request to `CreateAudienceList` is necessary to create an audience list of
- * users, and then second, this method is used to export those users in the
- * audience list to a Google Sheet.
- *
- * See [Creating an Audience
- * List](https://developers.google.com/analytics/devguides/reporting/data/v1/audience-list-basics)
- * for an introduction to Audience Lists with examples.
- *
- * Audiences in Google Analytics 4 allow you to segment your users in the ways
- * that are important to your business. To learn more, see
- * https://support.google.com/analytics/answer/9267572.
- *
- * This method is introduced at alpha stability with the intention of
- * gathering feedback on syntax and capabilities before entering beta. To give
- * your feedback on this API, complete the
- * [Google Analytics Audience Export API
- * Feedback](https://forms.gle/EeA5u5LW6PEggtCEA) form.
- *
- * @param string $formattedName The name of the audience list to retrieve users from.
- *                              Format: `properties/{property}/audienceLists/{audience_list}`
- *                              Please see {@see AlphaAnalyticsDataClient::audienceListName()} for help formatting this field.
