I couldn't get this to work with the default model because it's overloaded, but I tried flash-lite, which at least gave me a response, but it only presents an actual UI 1/3rd of the time that I tried the suggested questions in the demo, and otherwise it attempts to ask me a question which doesn't present a ui at all or even do anything in the app -- i had to look at the logs to see what it was trying to do.
