In Hub, a group is used as a resource in a project. The group defines how a collection of users gains access to the project. The access rights are defined by assigning one or more roles to the group.
In addition to the default user groups, you can create as many user groups as you need for your Hub instance.
You must add a group to a project to be able to use it later, for example, to use it as a group of assignees in a project.
Click the Create User Group button.
Note that all of the groups in Hub are subgroups of the All Users group. Any new group inherits all of the roles that are assigned to the All Users group.
John can create, read, and update the groups that he wants to use to assign roles in project A. He cannot see groups that are only linked to project B.
