What about nostr:npub1h2685kkxa4q50qpexuae9geqep7frr0u8t8pcy9zj0xnza9phvtsnkd9tm? I added my test npub, configured Pokey to listen to the relevant relays, and had another WH user send me a message - no notification from Pokey
Discussion
The difficulty lies in the obfuscated metadata, on the relay is only a event with cypher text, a random group ID, signed by a random key, and those continuously rotate for a group. So White Noise would have to communicate to pokey for which group IDs to look for, a non trivial change to the code.
