Have you ever wondered what Platform Event-triggered Flows do?
Here is a use case to demonstrate this functionality:
Send random customer satisfaction surveys when cases are closed. Send random surveys when customers update their addresses. Multiple record-triggered flows will help you achieve this, but subflows are not available in record-triggered flows at his point, will you have to repeat the survey generation in all these flows? Not necessarily. You can use platform events for this purpose. Watch this video see how it is done step-by-step.
