Screenshots show that there will be a "Create group" button underneath the search bar, and you can then save that group for quick access later. So you can select your three bands and name the group "BFFs" for example. Right now, it seems that the feature only supports up to four people however, even though a previous test showed that it supported up to seven.
That aforementioned test also showed that there could be a low-light mode for nighttime conversations and an in-progress feature. Otherwise we do not know much about it. That said, since the group chat is already live in a few countries, it will probably not be long before it arrives as well.
