Describe the bug
04-semantic-kernel-tool copy.ipynb is a code sample to demonstrate how function calling works. The main function of this sample code is written to display what function is called and what result they've returned. However, this part doesn't work: the response contains nothing but StreamingTextContent.

To Reproduce
Steps to reproduce the behavior:

1. Run 04-semantic-kernel-tool copy.ipynb
2. See the response of agent.invoke_stream doesn't show any FunctionCallContent nor FunctionResultContent.

Expected behavior
There should be FunctionCallContent and FunctionResultContent in the display.
