Internal users or groups. You select the type of privileges to grant, either:
Viewer. The Grantee can see the content of the task list, but cannot make any changes to the contents of the task list.
Manager. The Grantee has permission to create tasks and edit and delete tasks from your task list.
Admin. The Grantee has permission to create tasks and edit and delete tasks from your task list and to share your task list with others.
