To make an Apex method callable from a Lightning Web Component, you need to annotate the method with
@AuraEnabled and mark it as cacheable if it's only retrieving data without modifying it. Additionally, the method must be public to be accessible from the component.
Line 04: Needs @AuraEnabled(cacheable=true) to allow the method to be called from the Lightning Web Component and indicate that the method doesn't modify any data, making it suitable for caching.
Line 09: The method getFiveMostRecent should not be private because private methods cannot be called from a Lightning Web Component. Changing it to public (or default, which is equivalent to public within the same namespace) is required.
