can the wpmudev chat plugin be used as private chat? i.e. site admin to individual visitor

Hi can the chat plugin - https://premium.wpmudev.org/project/wordpress-chat-plugin/

be used as a visitor chat window similar to this - https://www.zopim.com/

Have tried going through the settings and couldn't find this maybe i missed it ? or the plugin is designed more like the wpmudev live group chats?

Thanks
tom
