Create Nostr private chats for subscribers members

Context

For a product A, with type = Subscription, create a private NostR chat with every active member

Needs

• Nostr possibility to create private channel / private message with more than 1 person
• Create a private channel with [Bootik name] - [Subscription product name] as title
• Allow every NostR npub with corresponding "active" status from List active "subscription" type product customers #224 in it
• On product subscription, allow to whitelist non-subscriber npub (for example, I want to add authors to a private channel dedicated to their last book or global work subscribers, without them being subscribers themselves)
• Each time a subscriber's statut is updated (except if he/she is whitelisted), the user is added or removed from the private group

Note

• Only info I found so far about possibility to create private chat on NostR with 3+ people is this : https://twitter.com/ImperviousAi/status/1627545578900164616
  • fun fact, I was invited randomly to a test group of NIP-29 feature ( NIP-29: Simple Groups nostr-protocol/nips#566 ), so this it was to follow for simple group chat
• If there's no new about it on NostR or if it's too restrictive, we can PoC the feature with a Keybase integration instead of NostR, following Prototype notifications on Keybase #34
