API to start new chat at anytime

Create an API where we can opt to show the "Start new conversation" button at all times on the modal.

Would love to have the start new chat button always appear right above the footer so the user can start a new chat anytime, in an intuitive manner. I noticed that Front recently released this functionality via the “undo” button on the top right hand corner of the modal. This is useful, but is not as intuitive for users. It would be ideal if there was an API which we could call to add that button in the chat window at all times.
