Which of the following is NOT a use case for local actions?

The choice indicating that automatically deleting old records from the database is not a use case for local actions is indeed correct. Local actions are designed to facilitate user interactions within the user interface, often enhancing the user experience during a flow by allowing specific tasks that relate to the navigation or presentation of information.

For instance, opening a related article in another window or tab and displaying a record created in flow in another tab are interactions that directly engage with the user's browsing experience. Additionally, closing a tab when a flow completes is a user-focused action that aids in streamlining the workflow within the interface.

In contrast, automatically deleting records from the database is an operation that typically falls under backend processes or a different aspect of Salesforce automation, rather than being a local action. This type of task is usually handled through database triggers, batch processes, or scheduled jobs that do not involve immediate user interaction within the interface, which is central to the function of local actions.
