😱 Sounds new to me; haven't walked that path yet. However having a quick view of the paylinks addon below `advanced options` there's a entry for nostr zapping; couldn't that help, maybe?
I can create an address inside the Paylinks extension but it never creates a .well-known to go with it. I have patrick@lnbits.sats.love setup right now but https://lnbits.sats.love/.well-known/lnurlp/patrick doesn't show the user.

That will make it so any received zaps get published by the node to your nostr relays. I had it enabled too but it shouldn't have anything to do with this problem though I admittedly don't have a clue why it's not working.
