To meet the business requirements and prevent the business logic that obtains the high value opportunities from being repeated in more than one place, the developer should take two actions: create a helper class that fetches the high value opportunities, and use custom metadata to hold the high value amount. By creating a helper class, the developer can encapsulate the logic that queries the opportunities based on the high value amount, and reuse the same class in both the trigger and the Lightning web component. By using custom metadata, the developer can store the high value amount as a configurable value that can be retrieved by the helper class, and avoid hard-coding the value in the code. This way, the developer can also easily change the value in the future without modifying the code. Calling the trigger from the Lightning web component would not work, as triggers are not meant to be invoked directly from the user interface, and would also violate the separation of concerns principle. Leaving the business logic code inside the trigger for efficiency would not work, as it would create code duplication and maintenance issues when the same logic is needed in the Lightning web component.
