Rocket chat mobile app notifications

as far as I understand:
popup notifications for new messages are only shown in the mobile app when using the push notifications service.
So there is no build in feature in the app that the app itself shows a popup and your mobile device with push notifications disabled on the rocket chat server
(e.g. like that popup the mobile browser is showing on arrival of new messages , when you are using rocket chat with a browser on your mobile device)

So the mobile app gives you only a notification when PUSH notifications are enabled on the rocket chat server, is this correct.

Thanks for you answers in advance

No. There is an in-app notification. For example, if someone write you a message, while you in other chat, that notification appears.
And if application in background push notifications come into play.
