Matomo in Magento

Hi everyone,
I am trying to use Matomo on a site build with Magento. The javascript code which I usually use on Wordpress sites did not work: although it was showing on the source code, Matomo did not receive any data to track and continued showing just the " Start tracking data" page. So we installed the recommended plugin Matomo Analytics Module for Magento 2 from but again, although inserting the right site ID and tracking URL it still does not track any data.
Did it happen to someone else as well? What should I do?

Thank you for your feedback!
