i have watched it but it wasn't very helpful:( in the video you are not using any other cards for safety:/ like, im using the first card for the main work. but if it cant recognize the users intent, the expression card will send the user to another card (the card for safety:) which asks the user to write what the use wrote before, but with different words. But as i said earlier, only when i say random things, the expression card works. When i say something related to my other intents it will just end the conversation.
