 * @category Class
 * @description When a request produces a response that exceeds the pageSize, pagination occurs. This means the response is divided into individual pages. To retrieve the next page or the previous page, you must pass the nextToken value or the previousToken value as the pageToken parameter in the next request. When you receive the last page, there will be no nextToken key in the pagination object.
