Wow. What DM protocol does it use? The new private nip? Or the original, visible to all?
In #0xchat v1.2.2, NIP-07 is supported, which means you can open the Nostr app in 0xchat and then authorize a login or signature.
BTW, wherostr.social looks great https://video.nostr.build/7cc158a5d3bfa578f54ae124c6dc5cbc22334cdf65b07d007516faf53ef31fca.mp4

We now support three types of DM, normal DM, Nip4 ; Gift-wrapped DM, Nip24; and secret chat.
