AI in Figma Design is not prototyping

Last weekend I was able to prompt the AI agent in canvas to create a prototype, with basic interactions, right on my file. Today, the chatbot says it can’t add interactions, and I have to do it myself, or use Figma Make. Is this a bug or a feature? Figma Make creates prototypes but when copying it to your Design file, it only copies the UI and not the interactions created. Could you let me know if this is a feature so that I can move on to Claude Design for prototypes?

Thanks!
