/**
 * Filters the recipient of the data request confirmation notification.

 * In a Multisite environment, this will default to the email address of the
 * network admin because, by default, single site admins do not have the
 * capabilities required to process requests. Some networks may wish to
 * delegate those capabilities to a single-site admin, or a dedicated person
 * responsible for managing privacy requests.
 *
 * @since 4.9.6
 *
 * @param string          $email  The email address of the notification recipient.
 * @param WP_User_Request $request_data The request that is initiating the notification.
