 You can perform additional data transformation using the `@Transform()` decorator. For example, the following construct returns the name property of the `RoleEntity` instead of returning the whole object.

-@Transform(role => role.name)
+@Transform(({ value }) => value.name)
 role: RoleEntity;
 ```
