Cant get it to work

[SlirigHorcrux]

Hello i am using your plugin but it does not send a push notificiation for me, is there something wrong with these lines of code?

$notificationBuilder = new PayloadNotificationBuilder('my title');
$notificationBuilder->setBody('body')
->setSound('default');

$notification = $notificationBuilder->build();

$optionBuilder = new OptionsBuilder();

$deviceResponse = FCM::sendTo($userKey, $optionBuilder->build(), $notification);

Hello

It looks ok, are you sure about your client implementation ?
Your token is valid ?
your key is valid ?

Best regards,
