How to avoid [Disqus] Discussion duplication when using Pagination?

hello guys, I am having problem with Disqus + laravel pagination. I have a post model where a post have minipost and for each post i want it to contain 5 minipost.. when I navigate to the 2nd pagination page the Disqus Discussion got auto generated for the 2nd page.. How can I avoid this duplication?

<div id="disqus_thread"></div>
<script>
    var disqus_config = function () {
        this.page.url = route('home');
        this.page.identifier = $slug; // Replace PAGE_IDENTIFIER with your page's unique identifier variable
    };

    (function() { // DON'T EDIT BELOW THIS LINE
    var d = document, s = d.createElement('script');

    s.src = '//testblog.disqus.com/embed.js';

    s.setAttribute('data-timestamp', +new Date());
    (d.head || d.body).appendChild(s);
    })();
</script>

The code

$posts = Post::where('slug', $slug)->firstOrFail()->minipost()->orderBy('created_at', 'desc')->paginate(5);
