I granted permission for a site to send me push notifications on my desktop, and now I would like to revoke that permissions.
While I can change the delivery permissions in Safari to decline push notifications from that site, my understanding is that this simply prevents them from being displayed, but does not disassociate my device from the specific server sending those push notifications.
How can I completely de-register for push notifications from a given website or service, after originally agreeing to receive push notifications?
