XMPP - How do I delete all messages between two jids, but only for one user?

Question

Problem: I want to delete all the messages (and thread) from one side of an equation between two users, A and B. I have no idea if this is even possible and if so, how.

I have the:

• jid of each user
• an XMPP library in JS (custom) that allows me to send IQ or any other type of stanza.

For example, this is how I get my friends (roster) list:

  async getFriends() {
    const requestId = this.sendStanza(
      'iq',
      { type: 'get' },
      (stanza) => stanza.c('query', { xmlns: 'jabber:iq:roster' }),
    )
    const result = await this.once('*', requestId);
    const requests = result.children[0].children.map(child => child.attrs.jid);
    return requests;
  }

Hopefully this is enough for someone to advise me. Thanks.

If you have full access to the client logic, you can implement your own logic, for instance, you can send an IQ stanza with a specific name space (xmlns) along with some elements/attributes, when the receiving side receives that IQ, it will do whatever logic you want (delete messages, thread, etc..)

Check this out: https://xmpp.org/extensions/xep-0424.html it is an extension to delete (retract) single message.
