Explanation
It is preferable to extend the Salesforce B2B Commerce remote invocation object instead of using the standard Salesforce remote action invocation manager for two reasons:
* The APEX method called by the remote action will be passed as a Salesforce B2B Commerce context object, which contains useful information such as the current user, cart, storefront, and configuration settings. This can simplify the development and testing of the remote action.
* The Salesforce B2B Commerce logger can be utilized in the remote action, which allows logging messages and errors to the debug log or to a custom object. This can facilitate debugging and troubleshooting of the remote action.
