[giuliaghisini]

in particular:

• trackerUrl
• srcUrl

Suggestion: add it in src/utils.js like:

.... **const trackerUrl = window.env?.RAZZLE_MATOMO_TRACKER_URL || config.settings.matomoTrackerUrl || undefined;

  const srcUrl =
    window.env?.RAZZLE_MATOMO_SRC_URL ||
    config.settings.matomoSrcUrl ||
    undefined;**

  if (siteId) {
    _matomo.instance = createInstance({
      urlBase,
      siteId,
      **trackerUrl,
      srcUrl,**
    });
  } else {
    /* eslint-disable-next-line */
    console.warn(
      'Matomo SiteID is not defined, page actions will not be tracked',
    );
  }
