No push notification received when eufy app is not logged in

I installed eufy cam 2 Pro two days ago. All works fine but ……> I do receive push notifications when I am logged in with the eufy security app. When I am not logged in I do not get any notifications when detection occur. Does this mean that I permanently need to be logged in with the app ? 24/7/365 ?
All notification buttons in the app, on my i-phone and i-pad are set active to allow push notifications.
Can anyone help me, please. Can anyone confirm that me assumption is correct.
Thank you very much.
