how to implement this.
@session.on("user_state_changed")
    def _on_user_state_changed(ev: UserStateChangedEvent):
        if ev.new_state == "away":
            session.generate_reply(instructions="ask user if they are still there")

Thanks for reaching out, Bryner. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.


To implement the `@session.on("user_state_changed")` decorator in LiveKit, follow these steps:

1. *Import Necessary Modules:* Import modules like `AgentSession`, `UserStateChangedEvent`, and plugins for VAD, STT, LLM, and TTS.
2. *Set Up the Agent Session:* Initialize the session with plugins and configure `user_away_timeout` to detect inactivity.
3. *Define an Inactivity Task:* Create an async function to handle user inactivity by generating replies and closing the session if needed.
4. *Implement the State Change Handler:* Use `@session.on("user_state_changed")` to listen for state changes. Start the inactivity task when the user becomes "away" and cancel it when they are active again.
5. *Start the Agent Session:* Begin the session with the agent and handle setup tasks.
6. *Run the Agent:* Use the CLI to execute the agent.
