Azure data factory pipeline failure trigger execute only last pipeline (Add Screenshot)

Question

As you can see, the alarm is not triggered when copy 6, the last pipeline, succeeds.

I want each copy pipeline to work regardless of the success or failure of the previous work. But if fails, I want it to trigger Webhook to send me an alarm.

Now, even if I connect the fail line (red line) to the web hook, it doesn't trigger the web hook from copy 1 to copy 5. If you look at capture 2, you can see that there is no web hook in the execution list because copy 6 is successful.
