How do you find out from either 9734 or 9735 events who sent the zap? I have a tag anon on the 9734 event starting with pzap1... Amethyst is showing me on the notifications the real sender of the zap, so I assume there is a way to somehow extract the sender from this anon pzap1... do you guys know how to do that? nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z
