How do I make zaps work and get reported with BTCPayServer? I have lightning address, I receive zaps, but people who zap me do not see the zap. So the invoice is paid. The nostr plugin says on top: "For Zaps, just enable a lightning address. None of the nostr settings on this page are needed for zaps anymore.". So how is the successful zap signed and published? Am I missing something? How does it work? :)
