Swift - When receiving a silent notification decide whether to show an alert or not

Question

I need your help,

I wanted to ask you 3 simple questions, where one goes in consequence of the other. Basically I want to limit to users the number of notifications they receive. Since it is a group chat and they are constantly receiving push. The idea is that I will get a push silent from a group, if this group did not send any push for 30 minutes, what I will do is show the push, if on the contrary less than 30 minutes ago we do not show the push. And that is why, I wanted to `regumber the following:

Is it possible to receive a silent push notification afterwards to decide whether to display the alert or not?
If the answer is affirmative, how can it be done?
How do I do it when the app is in Background?

Thank you :)

Can you explain step 2 and 3 with an example from you or the Internet? Because I do not see anything. Thank you :) ! — Slytherin, Jun 17 '19 at 14:48

1 - Can I listen to silent notification from the Appdelegate on remoteNotification? 2 - Can I decide in the app kill whether or not to show silent notifications depending on the time that has passed? — Slytherin, Jun 17 '19 at 15:07
