If G Suite admin wants to find out details information about employees within your organization, still, some people even wanted to have even better service. G Suite admin needs better visibility into Google Groups across G Suite.
In addition to current state, when Google Contact itself is a group, you will see even more information to these Hovercards.
It is how Hovercards will work in Gmail:
When you hover a mouse over a group in Gmail, you will see one small card; you will see group members and other info such as:
Schedule an event with the group
Email the group
When you click on more info, you will see detail information if another user has permission to view them. Despite being the fact that this feature is currently available in the Gmail, but it will soon add to other G Suite apps in the future.
