UsingSecurity.stripInaccessibleensures compliance with field-level security (FLS) and prevents users from accessing fields they do not have permission to view. In this scenario:
The commission field is inaccessible to Sales Assistants, andSecurity.stripInaccessiblewill automatically remove this field from the result set.
It prevents runtime errors when a user without proper access attempts to retrieve restricted fields.
