Does the confirmation go to the subscriber, or to the subscribed system? (If I subscribe a 3rd party, do I get the confirmation or does the 3rd party?) Review use of "subscriber" throughout 2.4.3 and subsections.

Existing Wording:

The subscription confirmation step informs the subscriber of the details of Hub’s recently created subscription. For webhook subscriptions, the confirmation also verifies the intent of the subscriber and ensures that the subscriber actually controls the callback URL.
