Chatbot skip to next question if asked query not answered by the Customer.

Hi,
If we ask for email or phone number but the customer doesn’t provide than they keep getting the error message.
Rather there should be an option so that if no response is provided then they should be sent to next action item.
let’s say I want to send some chats to customer agent after they have provided email and phone number.
Now If they provide they will be sent to customer agent but if they don’t provide it then they will be getting same error message again and again
