In Microsoft Power Automate, every cloud flow must begin with a trigger. A trigger is the specific event that initiates the flow's execution. In the scenario described, the event is "when a new order is recorded in Microsoft Dataverse." Therefore, you must configure a Dataverse trigger (specifically the "When a row is added, modified or deleted" trigger) to "determine when the flow will start." Once the trigger fires, the flow proceeds to execute the subsequent steps, which are called actions (such as sending a message in Teams). A formula is used within triggers or actions to process data but cannot initiate a flow itself.
