How to Automatically Approve a Goal After Notification Expiration in BPM Worklist

Hello,

I would like to modify the BPM worklist, specifically for the ApprovePerformanceGoal task.

When an employee adds a goal, their manager receives a notification, allowing them to approve or reject it.

We want to implement a rule where, if the manager does not respond within 30 days, the notification should expire, and the goal should be automatically approved.

Currently, I have managed to set the notification to expire after 30 days, but the goal remains in a pending state (awaiting approval) rather than being automatically approved.

Could you please advise on how to achieve this automatic approval after expiration?

Thank you.
