Just in case they are folks who are still trying to figure this out, here is how you do it. Do a search in your contacts for the name of your group. If you didn't name your group don't worry, the number of people in your chat is substituted for not naming your group. Enter that number in your search, now will be able to see the icon to add more people to your chat. Hope this helps
