Hi I had a question, I was working on a chatbot where I had a single choice option, Say there is a question having single choice options "Yes" and "No" but instead of choosing the options, someone typed in something, so I want to print a custom message saying, Hey Invalid option please choose from above, I am not getting any hint, please help. I tried using the third endpoint to a custom node sayin it but it runs after 2nd attempt.
