 * <p>
 *             The

 * // const { MTurkClient, ListQualificationTypesCommand } = 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 = { // ListQualificationTypesRequest
 *   Query: "STRING_VALUE",
 *   MustBeRequestable: true || false, // required
 *   MustBeOwnedByCaller: true || false,
 *   NextToken: "STRING_VALUE",
 *   MaxResults: Number("int"),
 * };
 * const command = new ListQualificationTypesCommand(input);
 * const response = await client.send(command);
 * // { // ListQualificationTypesResponse
 * //   NumResults: Number("int"),
 * //   NextToken: "STRING_VALUE",
 * //   QualificationTypes: [ // QualificationTypeList
 * //     { // QualificationType
 * //       QualificationTypeId: "STRING_VALUE",
 * //       CreationTime: new Date("TIMESTAMP"),
 * //       Name: "STRING_VALUE",
 * //       Description: "STRING_VALUE",
 * //       Keywords: "STRING_VALUE",
 * //       QualificationTypeStatus: "Active" || "Inactive",
 * //       Test: "STRING_VALUE",
 * //       TestDurationInSeconds: Number("long"),
 * //       AnswerKey: "STRING_VALUE",
 * //       RetryDelayInSeconds: Number("long"),
 * //       IsRequestable: true || false,
