I'm willing to give it a try but have to admit after reading the relevant NIP's (NIP-19, NIP-01, i am confused how to properly encode the NEventId specifically where to get the relay hints.
So take these two notes:

First has 'r' tag hints as distinct tags (that's NIP65) -> multiple relays
Second has 'e' tag with the recommended relay -> one relay
Which relay hints am I supposed to use? And also, why does NEvent signing allow for multiple relay urls?
I know Coracle and Amethyst both provide nevents, so maybe hodlbod (nprofile…5gcs) or Vitor Pamplona (nprofile…pyug) can provide some advice/best practice.
