Function to bring in reviews for a slider?

I would like to build a slider (I will probably use Flickity or something similar) by pulling in recent reviews (preferably 4+ Stars).

I can’t just use the shortcode, because for the slider I would to use foreach to add the classes to each review.

The idea is to be able to use recent comments like a testimonial slider like a lot of landing pages use.

In the end I would want something like

<ul id=”slider-id” class=”carousel”>
<?php
$gdcomments= whatever_the_function_is(array(
‘numbercomments’ => 4, // Number of recent posts thumbnails to display
‘post_status’ => ‘publish’ // Show only the published posts
‘post_id’ => ‘421’ //make a slider for a specific post

));
foreach( $gdcomments as $somecomment ) : ?>
<div class=”carousel-item”>
<p> Comment text </p>
</div>

<?php endforeach; ?>
