Combining quic transport with the chat-with-rendezvous example

I am trying to modify the chat-with-rendezvous example to use quic transport by borrowing some code from the server example. The combined changes:

...
        priv, _, err := ic.GenerateECDSAKeyPair(rand.Reader)
        if err != nil {
                return nil, err
        }

        t, err := libp2pquic.NewTransport(priv, nil, nil, nil)
        return t, err

        // libp2p.New constructs a new libp2p Host. Other options can be added
        // here.
        host, err := libp2p.New(libp2p.ListenAddrs([]multiaddr.Multiaddr(config.ListenAddresses)...), libp2p.Transport(quicTransport))
        if err != nil {
                panic(err)
        }
...

Running it:
