Use case- We are trying to add Update opportunity card in New Activity on Opportunity Trigger type Automation (Activity- Duplicate Detected), but the Update Opportunity card is not visible.
The activity Duplicate Detected is a system activity and we cannot update the system activity. Hence, when we are using Duplicate Detected activity, we are unable to see update opportunity card. This is an expected behavior.
