You're right you have to use Firebase messaging to handle the notification when the app is terminated and that is not appropriate because you have to tell the backend developer to forward the notification to the Firebase
But in my country firebase is not available so I used the pusher package as an alternative for the notifications but if the pusher disconnected after the app is terminated it's useless to use the pusher for that
I hope they notice your issue and fix this in the next update
