I'm having some difficulty understanding NIP-89 nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft. I almost understand it, I think.

But if I get an unknown event kind=34550,  and I have a handler (31990) for that kind,  and it has a bunch of tags like (sorry I just stole one as an example):

["web","https://nostrudel.ninja/#/u/<bech32>","npub"],
["web","https://nostrudel.ninja/#/u/<bech32>","nprofile"],
["web","https://nostrudel.ninja/#/l/<bech32>","note"],
["web","https://nostrudel.ninja/#/l/<bech32>","nevent"],
["web","https://nostrudel.ninja/#/l/<bech32>","naddr"]

I am at a loss as to which of those URLs to call.  I don't have an npub, or nprofile, or note, or nevent, or naddr, or any bech32 at all.  What I have is an event with a kind I don't recognize.  I am at a loss as to how anybody could ever turn that into..... an nprofile.... ever.

Please explain.
