How to collect an audience for Vkontakte retargeting by the number of pages visited on the site?

Question

JavaScript

There is an online store with Vkontakte retarget.
The task is as follows:
if the visitor viewed less than 3 pages of goods - we collect in 1 audience
; if less than 5 - we collect in 2 audience
; if more than 5 - we collect in 3
audience I can't understand the pages.
For example. Thus, I implemented the addition of users who clicked on the "Add to Cart" button to the retarget audience.

$( document ).ready(function() {
  $('.btn-buy').on('click', function () {
    VK.Retargeting.Add(24856396);
  });
});
