Power Platform Community Forum Thread Details

I have created a topic in the PVA chatbot which starts with a trigger phrase if the user input matches the trigger phrase it displays a message and then asks a multiple choice question. But if the user input does not match the trigger phrase it does not show the required message but shows default message "Sorry I didn't understand" followed by multiple choice question. How can I change this default message and redirect to another topic if the user input does not matches the trigger phrase.
