What should an admin verify when adding a local action to a flow?

When adding a local action to a flow, it is essential for the admin to verify that the flow's type is Screen Flow. Local actions are specifically designed to be invoked from a screen flow, allowing users to perform tasks interactively within the flow.

Screen Flows provide a user interface where users can input data or make choices, making them suitable for local actions that require user input or interaction. This interactivity is vital for functionalities like collecting information, providing feedback, or guiding users through a series of steps.

The other options address aspects that are either limitations or not relevant when using local actions. For instance, local actions are not meant for Classic runtime or Visualforce components, and there’s no dependency on the Lightning experience being disabled. Therefore, confirming that the flow is a Screen Flow ensures the local actions can function as intended within that interactive environment.
