How can you use actions to perform tasks in the browser?

Using actions to perform tasks in the browser is best achieved by building or installing a local action. Local actions are designed to run within the context of a specific record or context in Salesforce. They enable users to execute a predefined action directly in the user interface without requiring a page refresh, providing a seamless user experience.

Local actions are particularly useful for streamlining workflows, allowing users to interact with the data efficiently. For instance, when a user engages with a local action, they can promptly update records, create new entries, or trigger specific processes without navigating away from their current page or losing context.

The other options do not directly apply to the use of actions for performing tasks in the browser. A global constant is used for defining static values across multiple components but does not relate to executing actions. Creating a record set is more about preparing data for use in reports or processes rather than executing tasks directly in the browser. Configuring user inputs allows for some interaction but does not inherently enable the execution of tasks in the browser itself. Thus, building or installing a local action is the most effective way to utilize actions for this purpose.
