 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { StorageGatewayClient, DeleteChapCredentialsCommand } from "@aws-sdk/client-storage-gateway"; // ES Modules import
 * // const { StorageGatewayClient, DeleteChapCredentialsCommand } = require("@aws-sdk/client-storage-gateway"); // CommonJS import
