Shared AR: how to get data from host when peer hasn't joined yet

I'm Stuck

I got myself a working version with a somewhat smaller & ‘neater’ logic:

  1. The peer joins.
  2. The host takes notice from the OnPeerAdded event and broadcasts the string to all Peers (but to himself):
void OnPeerAdded(PeerAddedArgs args)
    {
        Debug.LogFormat("Peer joined: {0}", args.Peer.Identifier);
        string str = $"MyText";
        byte[] bytes = Encoding.ASCII.GetBytes(str);
        if (_isHost)
            _networking.BroadcastData(tag: (uint)_MessageType.SendPeerMessage, data: bytes, transportType: TransportType.UnreliableUnordered, sendToSelf: false);
    }
  1. The peer receives the string at the OnDidReceiveDataFromPeer function, deserializes it, and calls the appropriate method. Like this:
....
     case _MessageType.SendPeerMessage:
            string str = Encoding.ASCII.GetString(data);
            _controller.DoSomethingWithTheString(str);
            break;
     }

Case closed. Thanks.
