i think the correct UX for this is something nostr:npub12gyrpse550melzx2ey69srfxlyd8svkxkg0mjcjkjr4zakqm2cnqwa3jj5 mentioned on our last dev call:

all private interactions should show up in your DMs. private likes, private zaps, private thread replies, etc.

this is similar to how instagram does it when you interact with anything "privately".

this way you don't need to make everything kind14 (DM). you can have giftwrapped kind-anything and have it show up into your DM inbox.
