WebSocket port is hard coded, prevents image retrieval when port is different than 8188

[eazypeasy]

I am running comfyui on port 8189 and using the following to start the app
flask --app 'gligen_gui:create_app(8189)' run --port 5000

However, gligen_gui\static\script.js has the port hardcoded

function initWebSocket() {
  const socket = new WebSocket('ws://127.0.0.1:8188/ws?clientId=1122');

This results in a network error when the image is generated and the app tries receive the generated image:
script.js:468 WebSocket connection to 'ws://127.0.0.1:8188/ws?clientId=1122' failed:
