How to set FW to show if aplication want to connect to internet?

Hello. Because my internet is limited I only want to allow some aps to connect to internet. How can I set my firewall to ask me, when anything want to connect to internet can do it or not? And although remember settings for some aps?

Change the firewall to custom ruleset mode and change the alert frequency to very high. With custom ruleset mode every application will ask permission to access the internet unless you have a rule created for it.
