If a Flow is added to a Lightning page, what happens upon load?

When a Flow is added to a Lightning page and the page loads, the Flow automatically executes and presents its first screen to the user. This initiation occurs immediately upon the page loading, allowing users to interact with the Flow right away without needing to take additional action.

This behavior is particularly useful in scenarios where immediate user engagement is desired, such as guiding users through a specific process or collecting data.

In contrast, other options describe scenarios that do not align with the default behavior of a Flow on a Lightning page. The Flow does not wait for user interaction before running its initial screen, nor does it run only after a delay. Thus, the automatic execution of the Flow upon loading the page enhances the user experience by providing instant access to the Flow's functionality.
