A Group is a custom group of employees defined by your organization and is another way to organize your org. After a group has been created, admins have the ability to edit or delete the group at any point in time.
Admins can create groups to make them automated or static:
Automated groups: Automatically adjust based on the set of filters chosen
Static groups: Do not automatically adjust and members must be edited manually

Navigate to Admin > Settings > People > Groups.
Select Create group.
Add a name and description for the group > Select Next.
Under Member Criteria, select the desired filters that users must meet to be included in the group.
