Adding a rule
A rule is a setting customization that you make that determines the access of a user or a group of users to features when you want that access to be different from the default. For example, if you want only certain users to create personalizations, your default setting for the option
would be disabled. By default, users cannot make personalization if the setting is disabled. Then, create a rule that can turn on , that is, personalizations would be enabled for those users.
