New feature: Sharing Groups to your portal. This new feature enables you to define Groups and control their visibility on your portal, whether "public or private."
When a group in shared to your portal, all members of the portal will be able to find the Group and access the content within that Group.
Users will find the Group within their Group Explore and join it. Whereas a private Group is only accessible by members added to it
