 * <p>Calls back Amazon Chime SDK messaging with a processing response message. This should be invoked from the processor Lambda. This is a developer API.</p>
 *          <p>You can return one of the following processing responses:</p>
 *          <ul>
 *             <li>
 *                <p>Update message content or metadata</p>
