Hi Steve,

You can use the standard dataminer security features to define what rights different users have in the system.

Rights are defined on a user group level.
For your specific case, you can have a look at the element rights.

More information on setting up user permissions can be found in our documentation (link).

If the user doesn’t have the right to create an element, you can’t trigger a notification, since they will not see the option to create elements.

If the user does have the right to create elements, you could use the notification to get an email when a user creates an element.
