How to install notification function by pop-up or banner

We are now developing a general kind of SNS by Adalo.

  1. Can we install the function of notification by pop-up or banner in a native mobile app?

  2. Can we do the same in a progressive web app?

SNS? Social Network System?

I am not sure with PWA, but iOS Apps in Adalo could do this.
I found out you also need right configuration when you publish on appconnect to do notifications properly.
