Thank you so much, Renzhi. All trip stages (Cancelled/In-Progress/Completed) require the driver to click (in our example, the driver always starts the trip in the app once the customer boards the vehicle) to continue to next steps in the app, so the mandatory actions performed in the app are regarded as important attributes that can be captured at trip level. By doing so, we'll also be able to quickly see how many drivers are currently on the road and have active trips. With that said, it will also appear in the events table as a status change event. Hopefully this answered your question, if not we can chat further offline.
