I would like to use the Chat Plugin like a live chat

Hello,

I would like to use the Chat Plugin like a live chat feature similar to Zopim. Not sure if this is possible. Basically I would like anyone who visits the site to click a live chat button and the chat plugin opens up. What I don't want is for anyone else on the site to see our chats and jump in.
Is this doable and if so how do I properly configure it?

Thanks.
