Urgent please: Custom Avatar Sample Code: How to set temperature?

Hi folks

Have a look at https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/samples/js/browser/avatar

There's a place where we can call the OpenAI endpoint with a prompt. We'd like to also send a temperature for this. Where do we set it? can't see it neither in the javascript source files

Any ideas will be very much appreciated!

Thanks!
