To check if a method has been registered by the client in LiveKit RPC and wait for it to be registered if not, you can use the following approach: 1. Check if a method is registered: Use the

isRpcMethodRegistered

method to verify if a method exists in the registered handlers.

let isRegistered = await room.isRpcMethodRegistered("yourMethodName")

2. Register the method if it is not already registered: If the method is not registered, use

registerRpcMethod

to add a new handler.

if (!isRegistered) {
    try await room.registerRpcMethod("yourMethodName") { data in
        // Implement your handler logic here
        return "Response from RPC method"
    }
}

3. Handle the case where the method is already registered: If the method is already registered, you can either leave it as-is or unregister it first using

unregisterRpcMethod

before registering a new handler.

if (isRegistered) {
    await room.unregisterRpcMethod("yourMethodName")
}
try await room.registerRpcMethod("yourMethodName") { data in
    // New handler implementation
}

By following these steps, you can ensure that the method is properly registered and ready for use. Let me know if you need further assistance!
