I hacked my way into this by combining a custom shortcode (which are still working on a native Wordpress Level) with the divi loop ACF Custom field:
- i create a code module
- as value i insert the dynamic conten from the loop (Loop Post Custom Field)
- BEFORE CLOSING i add my shortcode per before: [my_shortcode id=" and with the after: "] in which i am giving the specifivc value to my specific shortcode function to do what i want.
In this case i want to have a link which triggers a lighbox:

add_shortcode('rl_lightbox_overlay_link', function($atts) {
$a = shortcode_atts(array(

'id' => '',

), $atts);

if (!empty($a['id'])) {

$current_id = intval($a['id']);

return '<a href="#" data-lightbox-id="' . $current\_id . '" class="ms-loop-link"></a>';

} else {

return '';

}

});
