I got it working. Below is the correct code. I hope this will be useful to others for sending real time messaging.

Js Work

Controller Code

broadcast(new SendMessageEvent("Hi", 1))->toOthers();
//Here 1 is recepient ID

Event Code

class SendMessageEvent implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $Message;
    private $UserID;

    public function __construct($message, $RecepientID)
    {
        $this->Message = $message;
        $this->UserID = $RecepientID;
    }

    public function broadcastOn()
    {
        return new PrivateChannel('SendMessageChannel.' . $UserID);
    }

}
