 * <note>
 *             <p>This operation is not supported by directory buckets.</p>

 *          <p>Returns the notification configuration of a bucket.</p>
 *          <p>If notifications are not enabled on the bucket, the action returns an empty
 *             <code>NotificationConfiguration</code> element.</p>
 *          <p>By default, you must be the bucket owner to read the notification configuration of a
 *          bucket. However, the bucket owner can use a bucket policy to grant permission to other
 *          users to read this configuration with the <code>s3:GetBucketNotification</code>
 *          permission.</p>
 *          <p>When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.</p>
 *          <p>When you use this API operation with 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
 *             Error Codes</a>.</p>
 *          <p>For more information about setting and reading the notification configuration on a
 *          bucket, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html">Setting Up Notification of Bucket Events</a>. For more information about bucket
 *          policies, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/using-iam-policies.html">Using Bucket Policies</a>.</p>
