When the bot cannot receive a predictable response from the user, guidance will be provided with a list of items to select from. This can help the user to proceed to the next step even if they cannot answer well in the communication. Alternatively, the user can remove the window of suggestions and provide an answer to the bot again by rephrasing the original answer.
