Every flow contains a subflow that is run automatically. What is the name of this subflow?

In the context of Microsoft Power Automate, every flow has a primary operational component that serves as its main execution routine. This component is referred to as the Main subflow. The Main subflow is responsible for orchestrating the entire flow's actions and processes, ensuring that each step is executed in coordination with the others.

This structure allows the flow to effectively handle the tasks it is designed to perform, such as data manipulation, condition handling, and integration with other services. The Main subflow functions as the entry point for the flow's operations, automatically triggering the sequence of actions defined within the flow.

Other options such as Master, Core, and Initial may sound relevant but do not represent the standard terminology used in Power Automate to describe the primary execution path of a flow.
