[Unet] How to Use SendBytesToPlayer?

Hey guys!

Trying to use the SendBytesToPlayer() to send a serialized class to a specific player, but i dont get how to trigger a function on the other side to receive the data? can't see any example on the unity manual so i came here!

Need this:

1. Choose a destination player/connection

2. Choose an specific Network Channel Id

Am trying something like this, but idk what to do next?

     public void SendSocketMessage(GameObject playerObj) {
 
         CubeListMessage msg = new CubeListMessage();
         msg.resourcePosition = resourcePosition;
         msg.resourceRotation = resourceRotation;
         msg.resourceType = resourceType;
         msg.resourceColor = resourceColor;
         msg.resourceColor2 = resourceColor2;
         msg.resourceColor3 = resourceColor3;
 
         byte error;
         byte[] buffer = new byte[1024];
         Stream stream = new MemoryStream(buffer);
         BinaryFormatter formatter = new BinaryFormatter();
         formatter.Serialize(stream, msg);
         
         int bufferSize = 1024;
         NetworkServer.SendBytesToPlayer(playerObj,buffer, bufferSize, 1);
 
     }
