Python: [Bug]: Cannot approve tool usage from sub-agents

async def nonstreaming():
    chat_client = SomeChatClient()

    @tool(approval_mode="always_require")
    def get_weather_detail(location: Annotated[str, "The city and state, e.g. San Francisco, CA"]) -> str:
        answer = f"The weather in {location} is cloudy with a high of 15°C, humidity 88%."
        return answer

    # Create weather assistant as inner agent
    inner_agent = chat_client.as_agent(
        instructions="You are a helpful assistant that provides weather information to users.",
        description="Agent that provides weather information.",
        name="weather_agent",
        tools=[get_weather_detail],
    )

    # Create main Agent that uses inner agent as tool
    outer_agent = chat_client.as_agent(
        instructions=(
            "You are a helpful coordinator. When a user asks about weather, "
            "use the weather_agent_tool to get the information."
        ),
        description="Coordinator agent that delegates to the weather agent tool.",
        name="coordinator_agent",
        tools=[
            inner_agent.as_tool(
                name="weather_agent_tool",
                description="A weather agent tool that provides current weather information for any given location.",
                approval_mode='never_require'
            )
        ],
    )

    user_input = "What's the weather like in Amsterdam?"
    session = outer_agent.create_session()

    response = await outer_agent.run(user_input, session=session)
    new_inputs: list[Message] = []
    if response.user_input_requests:
        for req in response.user_input_requests:
            print(f'User input requested - Func name: {req.function_call.name}, Args: {req.function_call.arguments}')
            new_inputs.append(Message("user", [req.to_function_approval_response(True)]))

    print("\nRunning agent with new inputs after approvals...\n")
    response2 = await outer_agent.run(new_inputs, session=session)
    print(f"Final response: {response2}")

Result:

User input requested - Func name: get_weather_detail, Args: {"location":"Amsterdam, Netherlands"}

Running agent with new inputs after approvals...

Final response: I'm fetching the current weather in Amsterdam for you. One moment!


Here is the output when the tool approval model is set to `never_require`

Running agent with new inputs after approvals...

Final response: The current weather in Amsterdam is cloudy, with a high of 15°C and a humidity level of 88%.
