Send push notifications with Ionic 2 to users group in background

Question

I want to display a push notifications in background for a defined users group.

Exemple :

• Send Push for users in "group A" = User in group A show this push
• Send Push for users in "group A" = User in group B don't show this push

In Ionic i have not seen a callback or others to filter received push by criteria (group ID for exemple)

If you are using firebase, you can use subscribe to topic. You can also get more details in the docs
