buzzzie groups, or swarms are a way for you to organise your helpers into logical containers. You are able to create a group permission that allows any helper added to the group to access the statuses you choose for that group. 

For instance, you may choose to create a family group that contains your partner and your children. You may want these people to be able to view your live location, so you set up the group permission to do so. You then may want to create a Parents group and allow your parents to see when you arrive or leave a geofenced location, but restrict them from viewing your live location etc.
