I can get a unique id withInstanceId , but I get a bug like this on my block in dev console.

Expected:
<div id="deneme-carousel-1" class="owl-carousel owl-theme"></div><script>jQuery( document ).ready( function() { jQuery('#deneme-carousel-1').owlCarousel();</script>
Actual:
<div id="deneme-carousel-21" class="owl-carousel owl-theme"></div><script>jQuery( document ).ready( function() { jQuery('#deneme-carousel-21').owlCarousel();</script>


index.js
    save: withInstanceId( function( { instanceId} ) {
        return(
            <div id={`deneme-carousel-${ instanceId }`} className={ classnames( 'owl-carousel', 'owl-theme', className ) }>
            </div>
            <script>
                {'function() { jQuery(\'#'+`deneme-carousel-${instanceId}`+'\').owlCarousel();'}
            </script>
    } ),
