Thanks @James
I am not a programmer and I don’t really understand how this can be done.

The main problem for me is how to get an array of image URLs from the gallery field (it is part of a Options page) and how to make them a variable. I checked how a WP gallery shortcode is done https://www.advancedcustomfields.com/resources/gallery/ but instead of the IDs I need the URL. I also tried using implode to add commas between values, but couldn’t make it work.

Could you please guide me into the right direction to solve this??

My not-working code is below. Thanks!

<!-- trying to get the array of URLs -->
<?php 
$images = get_field('slideshow_gallery', 'option');

if( $images ): 
     foreach( $images as $image ): ?>
		<?php echo $image['url']; ?>,  
		<br>
	<?php endforeach; ?>
<?php endif; ?>
</div>

<!-- Put the URLs inside a div -->
<div id="dom-target" style="display: none;">
    <?php 
        $output = "image01", "image02", "image03";  //just a test
        echo htmlspecialchars($output); /* You have to escape because the result will not be valid HTML otherwise. */
    ?>
</div>

<!-- Put the content into a variable -->
<script>
    var div = document.getElementById("dom-target");
    var myData = div.textContent;
</script>

<script> /* Build backstretch slideshow */
  // Duration is the amount of time in between slides,
  // and fade is value that determines how quickly the next image will fade in
  $.backstretch([
	myData
	
  ], {
	duration: 3000, 
	fade: 750
});
</script>
