Trigger notification when new changes are merged

[jeshels]

Is it possible to set up an email notification when Fork Sync finds new changes to be synced?

According to Notifications for workflow runs, I can set up a notification for a successful run of Fork Sync. However, I would like to distinguish between a successful run in which nothing happens (since there are no new changes to merge), and a successful run where new changes were detected and merged. I would like to get notifications only for the latter.

How can I achieve that?

Additional details: I could subscribe for pull requests events, but since the Fork Sync workflow operates under my user, I suppose that GitHub suppresses the notification (under the assumption that a user doesn't need to be notified about his own actions).
