Hi. I think this example is up-to-date and works https://github.com/dkandalov/live-plugin/wiki/Google-auto-complete (it's in Groovy though). I should probably delete this gist to avoid confusion 🤔
Ah, I somehow missed that one, thank you!

Hey, this is pretty old and does not work. Would it be possible for you to update and convert this to Kotlin? I'd appreciate it. Thanks!
