Change required within the Matomo tracking code

Hello,

Currently, the code generated by Matomo Drupal Module (Matomo Tag Manager Feature) is:

<script>
var _mtm = window._mtm = window._mtm || [];
_mtm.push({"mtm.startTime": (new Date().getTime()), "event": "mtm.Start"});
var d = document, g = d.createElement("script"), s = d.getElementsByTagName("script")[0];
g.type = "text/javascript";
g.async =true;g.src=https://cdn.matomo.cloud/INSTANCE-NAME.matomo.cloud/CONTAINER-NAME.js;
s.parentNode.insertBefore(g, s);
</script>

And it should be instead:

<script>
var _mtm = window._mtm = window._mtm || [];
_mtm.push({'mtm.startTime': (new Date().getTime()), 'event': 'mtm.Start'});
(function() {
var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0];
g.async=true; g.src='https://cdn.matomo.cloud/INSTANCE-NAME.matomo.cloud/CONTAINER-NAME.js'; s.parentNode.insertBefore(g,s);
})();
</script>

It is a minor change required, just to add the Immediately Invoked Function Expression "()" so the script runs as soon as it is declared.
