/**
 * <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>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>
 *
 *          <p>The following action is related to <code>GetBucketNotification</code>:</p>
 *          <ul>
 *             <li>
 *                <p>
 *                   <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketNotification.html">PutBucketNotification</a>
 *                </p>
 *             </li>
 *          </ul>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { S3Client, GetBucketNotificationConfigurationCommand } from "@aws-sdk/client-s3"; // ES Modules import
 * // const { S3Client, GetBucketNotificationConfigurationCommand } = require("@aws-sdk/client-s3"); // CommonJS import
 * const client = new S3Client(config);
 * const command = new GetBucketNotificationConfigurationCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link GetBucketNotificationConfigurationCommandInput} for command's `input` shape.
 * @see {@link GetBucketNotificationConfigurationCommandOutput} for command's `response` shape.
 * @see {@link S3ClientResolvedConfig | config} for S3Client's `config` shape.
