Ensure that the 
destination_identity
in the 
perform_rpc
call matches the identity of the frontend participant you want to communicate with. how do I get the identity: what does the code refers to identity
Copy code
@room.local_participant.register_rpc_method("greet")
async def handle_greet(data: RpcInvocationData):
    print(f"Received greeting from {data.caller_identity}: {data.payload}")
    return f"Hello, {data.caller_identity}!"

Thanks for reaching out, Anigilaje. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
The 
identity
in the 
perform_rpc
call refers to the unique identifier of a participant in the room. This is used to target a specific participant for the RPC call. In your provided code, you can retrieve the identity of the caller using the 
caller_identity
property of the 
RpcInvocationData
object. This property contains the identity of the remote participant who initiated the RPC call. Sources: performRpc | callerIdentity | RpcInvocationData

can i sed the identity or this is the dfult one from the rpc function : destinationIdentity: Participant.Identity,
t
The 
destinationIdentity
parameter in the 
perform_rpc
function must be manually specified. It does not have a default value and requires you to explicitly set the identity of the participant you want to target for the RPC call. You can refer to the Participant.Identity documentation for more details. Sources: livekit.rtc API documentation | PerformRpcParams | LiveKit JS Client SDK - v2.8.1
m
give me an example of an identity
t
An example of a 
Participant.Identity
in LiveKit is a string value that uniquely identifies a participant in a room. For instance, it could be something like 
"user123"
or 
"john_doe"
. This identity is unique per room, and if multiple participants with the same identity join, only the most recent one will remain active. Sources: Participant | identity | Core API primitives | LiveKit Docs | Identity
