this seems cool, im just curious, does this mean you save these ephemeral nsecs somewhere so the client can use them later or? (ie, i assume they must be stored in the client local db, or.. i suppose in a nostr encrypted event for multi device)

doing something like this, seems cool. and now with self service expiration/delete by p-tag and auth relays.. 🤔 all coming together? 😎
