Pay attention that names of chats can differ depending on the template you are using.
Free (in all templates)- free 1-to-many chat
Private/Video chat - paid 1-to-1 chat
Group/ Text chat - paid 1-to-many chat
Voyeur/Phone call (disabled in Expert template) - customer can spy on what is happening in paid chats, but not able to write anything.
