        Every Apex class should have an explicit sharing mode declared. Use the `with sharing`
        or `without sharing` keywords on a class to specify whether sharing rules must be enforced.
        Use the `inherited sharing` keyword on an Apex class to run the class in the sharing mode
        of the class that called it.
