Thank you!
One more thing:
The file “services/backend.js” from the example code “Hello World” runs automatically and creates a local server when the extension starts or do, is this just for the example? Do I have to have all my backend outside of Twitch?
If I can have all my backend outside of Twitch, how do I communicate to the front-end that it has to start showing the data if I send the signal from “panel.html”?
