Notebook privileges, such as Public Template creation, Co-editing and Lock Section, are not default privileges given when your ScienceCloud team is created. These privileges are left up to the customer to determine which users will need them.
Typically, Co-editing and Lock Section are done for the entire set of users in a Team. However, when it comes to Public Template creation, this depends on how a customer wants to release this privilege. It can be set at the Team Admin level, for the entire set of users, or on a user-by-user basis.
Setting these privileges can be done by Support, so please submit a service request in the 3DSupport App to make any changes to your team configuration.
