Emulated Roku Device cannot be found in Harmony app

1

I’ve followed the docs for Emulated Roku to install the integration and have got the server up on running on my home assistant instance as confirmed by the returned xml file when making a request to the server from a browser as recommended. However when I try to scan for local devices OR finding a Roku 4 device in the Harmony app, the emualated Roku device can never be found by the app.

Here is my config:

emulated_roku:
  servers:
    - name: Home Assistant
      listen_port: 8099
      host_ip: 192.168.1.124
      upnp_bind_multicast: false

Pls could anyone elaborate on the following, what is the easiest way to get the advertiser.py script up and running on a windows machine for someone not so familar with command line / power shell?

Run the advertise.py helper script from the emulated_roku library directly somewhere else and point it to the emulated Roku API.
