Yeah! I do suggest to make a clear documentation about how it should be done, I will contribute if needed. It is super confusing now and no single NIP to look at 🫂😭 

 Maybe send a PR with some of this code to nostr-tools?  

 Good idea! 🫂 

 I should add nip40 expiration to the wrap too I think, if the event is OTP 

 Great idea  

 Done!
