Need some Docs or Sample on how to pass additional Headers via Option

[NoSoup4you2]

Hi,

was wondering if you can provide some sample of syntax on how to pass additional Headers via options in the SocketIoConfig

const config: SocketIoConfig = { url: 'https://nodejs.pub.pgtel.net', options: {} };

here is what i like to pass

transportOptions: {
    polling: {
      extraHeaders: {
        'x-clientid': 'abc'
      }
    }
  }
