Create a new file demo.py with the following code:

@cl.on_message  # this function will be called every time a user inputs a message in the UI
async def main(message: str):
    # this is an intermediate step
    await cl.Message(author="Tool 1", content=f"Response from tool1", indent=1).send()

    # send back the final answer
    await cl.Message(content=f"This is the final answer").send()

Now run it!

$ chainlit run demo.py -w
