Not working on iOS devices

[Shagun-29]

Notifications are received on android but not iOS devices.

 // fcm_id <--- for device
        $optionBuilder = new OptionsBuilder();
        $token = $fcm_id;
        $optionBuilder->setTimeToLive(60*20);
        $notificationBuilder = new PayloadNotificationBuilder($title);
        $notificationBuilder->setBody($builderMsg)->setSound('default');
        $dataBuilder = new PayloadDataBuilder();
        $dataBuilder->addData(['message' => "Message Sent"]);
        $option = $optionBuilder->build();
        $notification = $notificationBuilder->build();
        $data = $dataBuilder->build();
        $downstreamResponse = FCM::sendTo($token, $option, $notification, $data);
        $downstreamResponse->numberSuccess();
        $downstreamResponse->numberFailure();
        $downstreamResponse->numberModification();

Any luck with this issue? We can't figure it out.
