Access to Tool Call in Chat History

[RandyPatterson]

in .NET I'm trying to get access to the Tool Call History for a conversation. I would expect to find the message with a role of "Tool" in the response. but the response returned from IChatCompletionService.GetChatMessageContentAsync() does not contain any 'tool' role messages. Also, the ToolCalls collection property is always empty. SK is definetly making several tool calls before arriving at the correct answer. Is this a bug or am I missing something?

Using AzureOpenAI GPT-4o model.
