Detect what function calls where made by the agent

[ghita]

When processing the ChatMessageContent response from an agent, I attempt to detect function calls using the message.Items collection. Specifically, I check if an item is of type FunctionCallContent using the following code:

else if (item is FunctionCallContent functionCall)
{
    Console.WriteLine($" Function call content: [{item.GetType().Name}] {functionCall.Id}");
}

However, the detection of function calls does not work as expected. Even when the agent is configured to invoke functions automatically (FunctionChoiceBehavior.Auto()), the message.Items collection does not reliably contain FunctionCallContent items for function calls made by the agent

I can see that function got called though before I receive the response from agent.InvokeAsync(message, thread).
How can I tell the calls happened or not ?
