Publish to Twitch

Greetings
I’ve been having a chat with ChatGPT and “it” references some configuration that would allow me to publish entities from Home Assistant as overlays to a Twitch feed. Like switches and even camera streams. This seems like an odd suggestion since the official HA integration only mentions subscribing to a Twitch channel feed and set up the online status of this. It’s not what I looking for.
Can anyone shed light on this integration?

I used to do this by setting up a dashboard showing the information I wanted to overlay, then adding it as a cropped web page to StreamLabs. Not the sexiest method but it worked.
