How to get model from result

[code-junkie-403]

Hi, I'm trying to get the model used from function result. I'm using handlebar prompt template like below:

var templateFactory = new HandlebarsPromptTemplateFactory();
var template = File.ReadAllText("prompt_template.yaml"));
promptFunction = _kernel.CreateFunctionFromPromptYaml(template, templateFactory);
var result = await _kernel.InvokeAsync(_promptFunction, arguments, cancellationToken: cancellationToken);

I'm able to get token used from result metadata, but it doesn't have the model used. What's the best way to get the model?
