 *          <p> To use this operation, you must have permission to perform the

 *          and can grant it to others.</p>

 *          <p>To use this API operation against an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name.
 * If the Object Lambda access point alias in a request is not valid, the error code <code>InvalidAccessPointAliasError</code> is returned.
 * For more information about <code>InvalidAccessPointAliasError</code>, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/ErrorResponses.html#ErrorCodeList">List of
