如何在一个事件中广播多个频道？

Question

I have a custom event that implements ShouldBroadcastNow and broadcasts to a public channel.

As the broadcastOn function just returns one channel.

I've already tried to create a custom listener but couldn't implement ShouldBroadcastNow

 public function broadcastOn()
{
    // foreach($this->ticket->intersectRouteDetails);
    return new Channel('route-details.'.$this->ticket->routeDetails->id);
}

what I need is a way to loop with the commented collection to change the channel name.

Is there a way to broadcast multiple channels in this event?

Thanks
