What is the primary function of the Debug button in Flow Builder?

The primary function of the Debug button in Flow Builder is to display details for debugging the flow. When users click the Debug button, they can test the flow in a controlled environment, allowing them to see how the flow operates step-by-step. This feature provides detailed insights into the execution process, highlighting variable values, decision outcomes, and the path taken through the flow.

This functionality is essential for identifying and resolving issues within the flow, as it enables users to observe and analyze the behavior of the flow in real-time without permanently processing any data. By providing this detailed information, the Debug button empowers users to refine their flows effectively, ensuring they work as intended before being activated for end-users.
