add scripts after accept cookie

Hi.

I need help with my script and cookie

I have this script that adds a widget to the website:

<script type="text/javascript">
(function(d, w, s) {
var widgetHash = 'ldPlpmhFEP2znaSryO0B', bch = d.createElement(s); bch.type = 'text/javascript'; bch.async = true;
bch.src = '//widgets.binotel.com/chat/widgets/' + widgetHash + '.js';
var sn = d.getElementsByTagName(s)[0]; sn.parentNode.insertBefore(bch, sn);
})(document, window, 'script');
</script>

The plugin blocks it, and the widget is not displayed on the site.
How can I allow this script to execute only after the user accepts the cookies?
