What does the green bullet at the beginning of a microflow indicate?

The green bullet at the beginning of a microflow signifies the starting point of that microflow. It serves as a clear visual indicator within the Mendix modeler, guiding developers to understand from where the execution of the microflow initiates. This starting point is crucial, as it allows the user to trace the logic flow of the microflow clearly and effectively. In the context of building applications, recognizing the entry point of a microflow helps ensure that all subsequent actions and decisions are appropriately structured and executed based on the defined logic.
