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

 * const config = {}; // type is BackupGatewayClientConfig
 * const client = new BackupGatewayClient(config);
 * const input = { // UpdateGatewaySoftwareNowInput
 *   GatewayArn: "STRING_VALUE", // required
 * };
 * const command = new UpdateGatewaySoftwareNowCommand(input);
 * const response = await client.send(command);
 * // { // UpdateGatewaySoftwareNowOutput
 * //   GatewayArn: "STRING_VALUE",
 * // };
