This flow does not trigger any special in-chat 1-to-1 chat process such as Chatfuel correct? (You are in this mode until that 1-to-1 chat session ends and then the normal bot logic picks back up.) You are simply asking for a question and an email address and giving a text response yes?
Speaking of which, how does the web widget work: are there simple ways to allow 1-to-1 chat via that interface?
