I have built a BOT using AMAZON Lex and Lambda and its working well.  However, if the BoT cant solve the users issue, they will then transfer to Live Agent.  I can open a liv agent session from the BoT, but I cant find a way to pass over the conversation history, and also a new window opens which will confuse the user.  I have my AMAZON BoT exposed on a comminities VF page.

Any idea how to have live agent import an existing conversation, or how to have it keep the current window?
