How i able to work with pagination of custom woocommerce shop page?

Question

Hi I have created a custom product archive page in woocommerce and created a custom design for the pagination as well..but i unable to make it dynamic. Have any idea how to work with pagination? My code of reference is below-

I am trying to go to the second page with tha pagination but it is not working. I have searched most of the forum but i did not get much help. Can you please help me to solve this?

<?php
/**
 * The Template for displaying product archives, including the main shop page which is a post type archive
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/archive-product.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce\Templates
 * @version 3.4.0
