Add an option to start zobot when user clicks the Chat with Us button

I would like to have an option to start the zobot when user clicks on "Chat with us"  button when chat widget is maximized that way visitors could see first the homepage and decide which channel they would like to use to connect, or to see the quicke help articles and banners on the chat window hompage.  instead of the zobot engaging right away and  past the  homepage
