How to send a notification to the client immediately after connection?

Question

Laravel

Event:

class PlaylistTitleUpdate implements ShouldBroadcast
{
/*.......*/
    public function broadcastOn()
    {
        return new PresenceChannel('playlist.'.$this->playlist->slug);
    }
/*.......*/
}

js code:

window.Echo.join(`playlist.novoe`)
    .here((users) => {})
    .joining((user) => {})
    .leaving((user) => {})
    .listen('PlaylistTitleUpdate', (e) => {
        console.log(e);
    });

This code works great. Fires as it should when the corresponding event occurs on the server. But how can I get this data on the client right after the user has connected? While "puzzling" came two options: 1). B here send ajax request 2). We need some new event that will track the user's authorization and send data to this particular user via a private channel (although it's hard to imagine the implementation of such an approach in my head) Please help! I really want to believe that everything is much simpler - poke your nose into the documentation if you may have overlooked this moment! Thanks in advance
