Unable to Use FCM in nWidart Module Notification Class

[abhiburk]

Hey
I have implemented notification class using https://github.com/nWidart/laravel-modules and in that I am using method from toFcm but when I send notification through this class I get an error
Call to undefined method Modules\Blog\Notifications\NotifyBlogChannel::toFcm()

When I use same toFcm method in Laravel Default channel (in app/notification) then that works perfectly.
It seem it doesn't work in Module Notifications Classes
