As it is now, there is no way for a chat visitors to close the chat, instead of either waiting in the middle of a chat flow without reaching an end of path, or getting redirected to our inbox when it isn't necessary or if they have found the answer before we could respond.
This is especially inconvenient as there is currently no way to redirect the client to restart and/or go back in chatbot flow (vote for this feature here!)
This would be amazing as it would allow us to be certain that a customer's issue has been resolved and will simplify our life.
