How to use the appium-ios-device.utilities.connectPort function in appium-ios-device

this.serverSocket = net.createServer(async (localSocket) => {
      try {
        const remoteSocket = await utilities.connectPort(this.udid, this.deviceport);
        remoteSocket.on('close', () => localSocket.end());
        remoteSocket.on('error', (e) => {
          // not all remote socket errors are critical for the user
          this.log.info(e.message);
          this.log.debug(e);
        });
        localSocket.on('close', () => remoteSocket.end());
        localSocket.on('error', (e) => this.log.warn(e.message));
        localSocket.pipe(remoteSocket);
        remoteSocket.pipe(localSocket);
      } catch (e) {
        this.log.error(e);
        localSocket.end();
      }
    });
