Problem with `socket.io-prometheus-metrics` about excalidraw-backend HOT 2 OPEN

Good point. Would you like to send a PR making it optional with an env variable?

Hi, can you help with this issue?

I set the port to 9091 in the index.ts file, but the drawings I made do not appear on the other user's screen. I get "WebSocket connection failed error" in the console

// listens on host:9090/metrics
prometheus.metrics(io, {
    port:9091,
    collectDefaultMetrics: true
});
