Using this plugin AND MTM ?

Hi,

I’ve been using your excellent plugin for 2 years ago, and it works very well with a personal Matomo instance on my server.
For now, I put tracking code in setting field “Enter manually”, and it looks like that:

<!-- Matomo -->
<script type="text/javascript">
  var _paq = window._paq || [];
_paq.push([function() {
         var self = this; function getOriginalVisitorCookieTimeout() {
                              var now = new Date(), 
                             nowTs = Math.round(now.getTime() / 1000), 
                             visitorInfo = self.getVisitorInfo(); 
                            var createTs = parseInt(visitorInfo[2]); 
                            var cookieTimeout = 33696000; // 13 mois en secondes        
                            var originalTimeout = createTs + cookieTimeout - nowTs; 
                            return originalTimeout;  }
          this.setVisitorCookieTimeout( getOriginalVisitorCookieTimeout() );  }]);
  /* tracker methods like "setCustomDimension" should be called before "trackPageView" */
  _paq.push(['trackPageView']);
  _paq.push(['enableLinkTracking']);
  (function() {
    var u="https://myserver.tld/";
    _paq.push(['setTrackerUrl', u+'matomo.php']);
    _paq.push(['setSiteId', '3']);
    var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0];
    g.type='text/javascript'; g.async=true; g.defer=true; g.src=u+'matomo.js'; s.parentNode.insertBefore(g,s);
  })();
// accurately measure the time spent in the visit
_paq.push(['enableHeartBeatTimer']);
</script>
<!-- End Matomo Code -->

But, now, I would like to use Matomo Tag Manager in order to track goals, and some specific behaviors (for example sroll depth).

My question: Can I put the container code just after my actual tracking code ?

Ronan Hello says on his website about Matomo (https://ronan-hello.fr/series/matomo/configuration-matomo-tag-manager) , about the container code:

<!-- Matomo Tag Manager -->
<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.async=true; g.src='https://matomo.mon-site.fr/js/container_XXxxxXXXxx'; s.parentNode.insertBefore(g,s);
</script>
<!-- End Matomo Tag Manager -->

……If you had already set up Matomo in the traditional way, you will need to “remember to remove the old tracking code to avoid duplication.”

So can I let my previous dode and just and this one (adapted to my matomo server and caontainer of course) ?

Thanks a lot for any advices.
Best regards
