repmgrd_upstream_disconnect event not call the event_notification_command

I want the repmgrd_upstream_disconnect event information to calculate the failover time, but the repmgrd_upstream_disconnect not notification;
repmgrd_upstream_disconnect event log:

code in repmgrd-physical.c:1598 call function create_event_record to notify event，but the function create_event_record is not the notification function ,so the repmgrd_upstream_disconnect event not call the notification script ， the repmgrd_upstream_disconnect event sholud call the create_event_notification to notifiy
