In Nostr it ask data in json format. And there are 6 items it is necessary to past into it might be more and some clients might understand it or not but 6 is required. The “kind” is determining what type is you are passing and I think kind 1 is the basic notes we are using. These are also so new to me and trying to understand but that’s my understanding from the previous cryptic note is: “For these basic notes we are using here, you can’t use and we should’t be able to use it but there are other kind of data that can passed on NOSTR and in some of them you can use”.
I might be wrong as I said I’m still trying to understand what’s going on here so keep that in mind :)
