From the Users page, you can add new users and manage their roles and status.
How to add a user?
To add a new user to your organization, click the “Add Team Member” button. Enter their email address and select a role within the organization: Organization Owner, Organization Admin, or Organization User.
How to enable, disable or delete a user?
You can enable or disable a user’s status to enable or limit their permissions to view or edit content. Disabling a user (toggling the Status button to off) will remove their user privileges, meaning they will not be able to access or edit content or collections or view private content. Disabling a user removes them from the organization until they are re-invited via the “Add Team Member” button. A disabled user becomes a registered user from the perspective of this organization, but will retain access permissions to other organizations they belong to.
