What is the event that ocurres when a participant information is updated? If this ocurres when a participant joins and prints their information
Copy code
@ctx.room.on("participant_connected")
    def on_participant_connected(participant: rtc.RemoteParticipant):
        <http://logger.info|logger.info>(f"new participant joined {participant.identity}")
What is the equivalent that fires when there is a change on the participant identity or attributes?

Thanks for reaching out, Santiago. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
In LiveKit, the event that occurs when a participant's information is updated depends on the specific type of update: • Metadata Updates: Use the event for metadata changes, such as 
participant(_:didUpdateMetadata:)
in Swift or 
ParticipantMetadataUpdatedEvent
in Flutter. • Attribute Updates: For changes in participant attributes, you can use 
participant(_:didUpdateAttributes:)
in Swift or 
RoomEvent.ParticipantAttributesChanged
in JavaScript. • Name Updates: For name changes, use 
participant(_:didUpdateName:)
in Swift or 
ParticipantNameUpdatedEvent
in Flutter. These events allow you to handle updates to participant information dynamically. Let me know if you need further clarification or examples!

Great! give me the code for python

Hey there! I totally get your confusion about participant updates in the LiveKit Python SDK. While there isn't a specific event for participant info changes, you can actually use the 
update_participant
method to modify participant details. Check out this handy example:
Copy code
async def update_participant(self, update: UpdateParticipantRequest) -> ParticipantInfo:
    """Updates a participant's metadata or permissions.

    Args:
        update (UpdateParticipantRequest): arg containing:
        - room: str - Room name
        - identity: str - Participant identity
        - metadata: str - New metadata
        - permission: ParticipantPermission - New permissions
        - name: str - New display name
        - attributes: dict[str, str] - Key-value attributes

    Returns:
        ParticipantInfo: Updated participant information
    """
I know it might not be exactly what you were hoping for in terms of real-time updates, but this method can help you manage participant information. Want to chat more about how we can work around this? I'm here to help! Sources: livekit.api.room_service API documentation
