If you use a flow step, the Power Automate flow must have an instant trigger. You should use the Common Data Service connector and the When a record is selected trigger.
The following screenshot shows how to add the When a record is selected trigger to a Power Automate flow:
Figure 13.12 – Configuring a flow for use in a business process flow
You must specify in the trigger the entity that was created when you created the business process flow, and not the primary entity, nor any of the entities used in the stages of the business process flow.
Only solution-aware flows can be added as a flow step.
