How to integrate multiple Android Applications using the same Laravel Application using multiple FCM sender keys

I am using brozot/laravel package for sending notification to users.

But I have multiple mobile apps (for each app I manage different server key and sender id) and I am using same laravel backend to send notifications to all different mobile apps.

How can I send notification to different app using different sender id (not using single sender id) with laravel brozot package?
