Describe the feature

ConversationHandlerFunctionProps has fewer configuration options compared to FunctionProps. For example, you cannot set the environment. This is useful for storing API keys when using external APIs.

Use case

I would like to use external APIs such as Tavily through tool calls. Instead of preparing a separate Function for that, I want to use it within a ConversationHandlerFunction. For reference, please take a look at this repository.
