This scenario is similar to non-blocking authentication, however, it’s not restricted to only one user.

Sending an asynchronous authentication request is pretty straightforward, you can do it with the async option.

This will return a conversation id identifying the authentication conversation, you should store it and catch it on a subscription, check Receiving authentication response - Subscribe section on how to manage this.

cid = @client.
    authentication.
    request("1112223334", async: true)

client.
    AuthenticationService().
    RequestAsync("1112223334", "conversation_id")

let res = await client.
    authentication().
    request("1112223334", { 'async': true })
