Peer to Peer chat app

[frankvp11]

Hello! This might be a dumb question, but I've been stuck on it for quite a few hours.
Is there a way that me and my friend can chat over libp2p? I'd like to use the peer discovery and connection so that he and I can chat via the terminal?
I saw the chat example, but I don't believe that works for two seperate laptops connected over wifi. When I ran it with my friend, we both got these when we tried dialer (one was listener in both cases):

node:internal/per_context/domexception:66
    ErrorCaptureStackTrace(this);
    ^
DOMException [TimeoutError]: The operation was aborted due to timeout
    at new DOMException (node:internal/per_context/domexception:66:5)
    at Timeout._onTimeout (node:internal/abort_controller:155:9)
    at listOnTimeout (node:internal/timers:588:17)
    at process.processTimers (node:internal/timers:523:7)

Node.js v22.19.0

Can someone point me to an example of what I'm looking for, and if this is the example that I need, why it's breaking?
I'd like to get this working, so any help would be greatly appreciated!

The demo chat app uses MDNS to discover local peers. You can get more debug information by running with the DEBUG environmental variable, e.g. DEBUG=libp2p* node index.js.

TBH just a demo and is not very robust. Have you tried the universal connectivity app? It's more polished and allows for things like making explicit connections between peers (for when MDNS is blocked, etc).
