The best technique to streamline the data upload is to update the primaryid__c field definition to mark it as an External Id. An external ID is a custom field that has the “External ID” attribute, meaning that it contains unique record identifiers from a system outside of Salesforce. When you select this option, the field becomes searchable in Salesforce and you can use it to integrate with external systems and import data more efficiently1. By marking the primaryid__c field as an external ID, the developer can use it to match the records in the CSV file with the existing records in the candidate_c object, without creating duplicates or errors2.

 To create a form that will create a record for a custom object, the developer can use a Dynamic Form, which is a Lightning App Builder component that allows you to customize the fields and sections of a record page layout1. A Dynamic Form can also use visibility rules to display different fields based on the user’s profile, role, or other criteria2. To add the functionality to the Account record page, the developer can use a Dynamic Action, which is a way to configure actions on a record page without code3. A Dynamic Action can also use visibility rules to show or hide actions based on the user’s profile, role, or other criteria4. To restrict the functionality to a small group of users, the developer can create a Custom Permission, which is a way to grant access to custom processes or apps5. A Custom Permission can be assigned to a permission set or a profile, and then assigned to the users who need it. References:

The fire() method is used to fire an Aura application event from a component controller or helper. This method takes the event instance as a parameter and broadcasts it to all components that are listening for that event type. The registerEvent() method is used to declare an event in a component markup, not to fire it. The emit() and fireEvent() methods are not valid methods for Aura application events. References:

A lightning component is a reusable unit of code that can be used to override the standard actions of an object, such as Edit, in Lightning Experience and the Salesforce mobile app1. A lightning component can provide a custom user interface and logic for the action, and can interact with the record data using the force:recordData component2. A lightning action, a lightning page, and a lightning flow are not valid options for overriding the standard Edit button for an object. References:
