GetStream Laravel - Cannot batchadd to notification - laravel-5.4

Question

I can't seem to use the batcher to copy an activity to notifications. I read from the docs
that there is a 100 limit to the TO field for copying activities, so i tried out using the batcher. but it does'nt seem to work. did I miss out something on the docs or on my code? if so, how do I get over the 100 limit?
$evtConvMention = array();
$evtConvMention[] = "event:{$event->id}";
$evtConvMention[] = "notification:1";
$evtConvMention[] = "notification:2";
$batcher = FeedManager::getClient()->batcher();
$batcher->addToMany([
"actor" => "App\User:{$user->id}",
"verb" => "eventpost",
"object" => "App\EventConversation:{$post->id}",
"foreign_id" => "App\EventConversation:{$post->id}"
], $evtConvMention);

The addToMany() call will have a similar limit. While I look into the PHP library a little more, it might be easier to use the To field in the activity payload itself.
$feed = FeedManager::getClient()->feed("event", $event->id);
$now = new \DateTime("now", new \DateTimeZone('Pacific/Nauru'));
$data = [
"actor" => "App\User:{$user->id}",
"verb" => "eventpost",
"object" => "App\EventConversation:{$post->id}",
"foreign_id" => "App\EventConversation:{$post->id}",
"time" => $now
];
$feed->addActivity($data);
We also HIGHLY recommend sending your own foreign_id and time fields in the payload as well (I've added an idea for the $now value in the code above, otherwise every feed will get its own unique record, which are a limited resource on your account.
If you have more than 100 notification feeds to write this into, it might be better to have the notification feeds for those users 'follow' the event feed. Then you don't need to use the to field at all.
