Previous/Next navigation on single post

Hi,
Thank you for the screenshot and link, I see your custom red buttons for the next / previous, if you add a custom class or ID to these then you can add the next and previous links to them with this function:

function custom_script(){
  ?>
  <script>
(function($){
  $(document).ready(function(){
    var getprev = $("a.avia-post-nav.avia-post-prev").attr("href");
    var getnext = $("a.avia-post-nav.avia-post-next").attr("href");
    $(".woocommerce-product-details__short-description .avia-buttonrow-wrap a.avia-button:nth-child(2)").attr("href", getprev);
    $(".woocommerce-product-details__short-description .avia-buttonrow-wrap a.avia-button:nth-child(3)").attr("href", getnext);
});
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'custom_script');

This code example was successfully used for products in a shop that had custom buttons similar to yours, but it needs to be modified to work for you.
After you add a custom class or ID we can assist further.

Best regards,
Mike
