Bonjour can find services that it created itself, but nothing else can

[MarshallOfSound]

Running the following in my app

const service = bonjour.publish({
  type: 'GPMDP',
  name: os.hostname(),
  port: 5672,
  txt: {
    API_VERSION,
  },
});

service.start();

The up event is fired for service but when I attempt to find the published service with this chrome app https://chrome.google.com/webstore/detail/mdns-browser/kipighjpklofchgbdgclfaoccdlghidp

It is not there. Is there some configuration step I am missing, or is there a trick to getting this to run on a device that already has Apple Bonjour running?
