If you want to create a chatbot service that will run in every room: 
meshagent service create --name "chatbot" --image docker.io/meshagent/sample-chatbot:0.0.31 --env="MESHAGENT_PORT=8090" --port "num=8090 type=meshagent.callable liveness=/ path=/agent participant_name=chatbot"
If you want to test the chatbot with a single room: 
meshagent service test --room my-room --name "chatbot" --image docker.io/meshagent/sample-chatbot:0.0.31 --env="MESHAGENT_PORT=8090" --port "num=8090 type=meshagent.callable liveness=/ path=/agent participant_name=chatbot"
Here is the chatbot service code if you want to create your own app: 
from meshagent.api import RequiredToolkit
from meshagent.agents.chat import ChatBot
from meshagent.openai import OpenAIResponsesAdapter
from meshagent.api.services import ServiceHost

import asyncio

service = ServiceHost()


@service.path("/agent")
class SimpleChatbot(ChatBot):
    def __init__(self):
        super().__init__(
            name="meshagent.chatbot",
            title="chatbot",
            description="an simple chatbot",
            rules=[],
            llm_adapter=OpenAIResponsesAdapter(),
            requires=[
                RequiredToolkit(
                    name="meshagent.markitdown",
                    tools=["markitdown_from_file"],
                ),
            ],
        )


asyncio.run(service.run())
