/**
 * <p>
 *             The
 *             <code>ListQualificationRequests</code>
 *             operation retrieves requests for Qualifications of a particular
 *             Qualification type. The owner of the Qualification type calls this
 *             operation to poll for pending requests, and accepts them using the
 *             AcceptQualification operation.
 *         </p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { MTurkClient, ListQualificationRequestsCommand } from "@aws-sdk/client-mturk"; // ES Modules import
 * // const { MTurkClient, ListQualificationRequestsCommand } = require("@aws-sdk/client-mturk"); // CommonJS import
 * // import type { MTurkClientConfig } from "@aws-sdk/client-mturk";
 * const config = {}; // type is MTurkClientConfig
 * const client = new MTurkClient(config);
 * const input = { // ListQualificationRequestsRequest
 *   QualificationTypeId: "STRING_VALUE",
 *   NextToken: "STRING_VALUE",
 *   MaxResults: Number("int"),
 * };
 * const command = new ListQualificationRequestsCommand(input);
 * const response = await client.send(command);
 * // { // ListQualificationRequestsResponse
 * //   NumResults: Number("int"),
 * //   NextToken: "STRING_VALUE",
 * //   QualificationRequests: [ // QualificationRequestList
 * //     { // QualificationRequest
 * //       QualificationRequestId: "STRING_VALUE",
 * //       QualificationTypeId: "STRING_VALUE",
 * //       WorkerId: "STRING_VALUE",
 * //       Test: "STRING_VALUE",
 * //       Answer: "STRING_VALUE",
 * //       SubmitTime: new Date("TIMESTAMP"),
 * //     },
 * //   ],
 * // };
 *
 * ```
