I tried to modify #[0]'s LnMe application to work with NIP-57 Zaps and I am too dumb to get it working. Modification to get the two added Nostr parameters on the URL are really easy and work great. That's the easy part. The hard part is getting the Nostr callback working. Doh. I guess I'll need to wait for a real developer to get Zaps working for self hosted folks.

that's the problematic part of NIP-57. Now all the LNURL tools and providers need to do this.
