for content in update.contents:

Error thrown on executing the AG_UI Chat client -

Traceback (most recent call last):
File "...\AG_UI_ChatClient.py", line 6, in
from agent_framework import Agent, ToolCallContent, ToolResultContent
ImportError: cannot import name 'ToolCallContent' from 'agent_framework' (...\Lib\site-packages\agent_framework_init_.py)

Proposed changes that are working -
............

Create AG-UI chat client

chat_client = AGUIChatClient(**endpoint**=server_url)

..........

Display tool calls and results

                    print(f"\n\033[95m[Calling tool: {tool_name}]\033[0m")
