You can exercise the Webhook Subscriptions permission by subscribe, read, renew and delete a subscription several times. Just ignore the n11s/ next to the endpoint. It's an internal path which is not meant be shown there.
@Phong Vu Thank you for your Answer on Zak's Question.
From my side, I can say that I have tried this answer many time, and it just doesn't register the permission as being used.
Is there something else I can try as I am urgently needing to get my client to start using the integration.

I have exercised the webhooks get post and delete at least 30 times. My graduation process is scripted so I execute all my endpoints dozens of times.... I'm logging all my api error codes and I'm sure that none of them have resulted in an error. I can confirm that I'm getting events over the webhooks. yet the graduation process indicates no webhooks have been executed and it's been about 24 hours.
