Interstitial Ads Setup

I want to implement a system in my app where an Interstitial Ad is shown after a WebView page loads 3 times.

After the ad is displayed and closed, the page load counter should reset, and again when the page loads 3 more times, another Interstitial Ad should be shown.

In short:

Page load count = 3 → Show Interstitial Ad

After ad is closed → Reset counter

Again after 3 page loads → Show Interstitial Ad

Is it possible to implement this page load counter + interstitial ad system using Nitron?

If yes, please provide guidance or an example.
