How to use auto invoke function calling in YAML prompt

[KishanJ98]

I have a YAML prompt and a GenerateImage KernelFunction which uses Dall-E to generate an image. However I want the SK to determine to call this function based on the intent of the user if it wants to generate an image.
I tried to use this:

function_choice_behavior:
              type: auto
              functions:
              - ChatPlugin.GenerateImage

This is the code I use to create the KernelFunction from YAML:

 var chatPrompt = EmbeddedResource.Read("ChatPrompt.yaml");
 var chatPromptFunction = Kernel.CreateFunctionFromPromptYaml(chatPrompt);

But this is not calling the method. If I put this in the prompt: {{ChatPlugin.GenerateImage}}, then the method is called, but it is called everytime regardless of the user wanting to generate an image or not.
Any ideas on how to do make this work?

@KishanJ98 - samples are coming this week to show off how to do function choice behavior. Docs are coming very soon also.
