How to use the @vendure/core.DefaultLogger.restoreOriginalLogLevel function in @vendure/core

const appModule = await import('@vendure/core/dist/app.module');
        try {
            DefaultLogger.hideNestBoostrapLogs();
            const app = await NestFactory.create(appModule.AppModule, { cors: config.cors, logger: false });
            let worker: INestMicroservice | undefined;
            await app.listen(config.port);
            if (config.workerOptions.runInMainProcess) {
                const workerModule = await import('@vendure/core/dist/worker/worker.module');
                worker = await NestFactory.createMicroservice(workerModule.WorkerModule, {
                    transport: config.workerOptions.transport,
                    logger: new Logger(),
                    options: config.workerOptions.options,
                });
                await worker.listenAsync();
            }
            DefaultLogger.restoreOriginalLogLevel();
            return [app, worker];
        } catch (e) {
            console.log(e);
            throw e;
        }
    }
}
