PushNotification: setMessage not defined

Hi I am getting the following error:

Call to undefined method Edujugon\PushNotification\Facades\PushNotification::setMessage()

This is my code:

$push = new PushNotification('apn');
        $push->setMessage([
            'aps' => [
                'alert' => [
                    'title' => 'This is the title',
                    'body' => 'This is the body'
                ],
                'sound' => 'default'

            ],
            'extraPayLoad' => [
                'custom' => 'My custom data',
            ]
        ])
        ->setDevicesToken(['DEVICE_TOKEN_HERE']);
$push->send();

Also if I use the facade I get success code but no notifications received, any ideas?
