iOS Question Apple store question

Hi,

I put an app in the store and it all worked fine.
The app_id is like jk.xxx.store

Now I made some changes, added the notification service.
In the develop system all ok.

Now I want to put in the store.
Must I make a new app id with the notification services,
like : jk.xxx.push
or do I have to edit and add the service to the old app_id : jk.xxx.store

When I change the app_id and upload to apple connect, is it a new app
for the store or an update.
