Which of the following is NOT a component of Flow Designer?

In Flow Designer, triggers, flow actions, and conditions are all integral components that work together to automate processes within the ServiceNow platform.

Triggers are the starting points of a flow, signaling when the flow should begin based on specific conditions or events. Flow actions are the discrete activities that the flow performs; these can include operations like sending notifications or updating records. Conditions allow flows to evaluate data and determine the path of execution based on criteria defined by the user.

In contrast to these components, a service desk is not a core element of Flow Designer. Instead, it represents a function or a module focused on managing service requests and incidents, allowing organizations to support their users efficiently. The service desk may utilize flows created in Flow Designer, but it does not constitute a component of the Flow Designer tool itself.
