Problem: We forgot to bring a raspberry pi and/or Arduino to do physical integrations. 

We did however have a JBL GO and a laptop.

The solution:

a tiny node.js server was set up to play a specified sound file on a laptop.

We exposed this using a dev tunnel, and in turn embedded this in a flow to trigger some fun sounds on our table.

This has many use cases. Since our agents are running unattended it is nice to have an audio notification when something happens.
