-| visible      | `bool` or `callable`   | **function ($context): mixed**<br> You can customize the visibility of fields by defining them as visible or not visible using a `bool` or your own custom logic by sending a `callable` that receives the `$context`. In introspection, the field will not be included in the result and if a query references that field, it will return a validation error.                             |
+| visible      | `bool` or `callable`   | Defaults to `true`. The given callable receives no arguments and is expected to return a `bool`, it is called once  when the field may be accessed. The field is treated as if it were not defined at all when this is `false`. |
