Local test does not notify webhook when Remove is executed

The problem is that in the local test items the add works fine, but the delete does not.

The webhook url is set in Deauthorization Notification.
The target URL is the webhook url of the development environment that is published for testing.

Nothing is set in General Features.

I have an additional question.
Is local testing a must?
Also, if there is a best way to do local testing, please answer.
I don’t know what the problem is, so please help me!
