Specifying a custom language model

[llamallion]

Can you help me understand how to specify a custom language model? My understanding is since this project uses a websocket I need to use this format:

var IAM_access_token = {access_token};
var wsURI = '{ws_url}/v1/recognize'

• '?access_token=' + IAM_access_token
• '&model=es-ES_BroadbandModel'
• '&language_customization_id={customization_id}';
  var websocket = new WebSocket(wsURI);

But I'm not sure where to pass this information, or how to hand it an access token and websocket URL. I'm sorry, I'm not much of a coder, I'm just having to stumble through this for a personal project.
