Google analytics isn’t showing purchases or conversions

Thanks for reaching out @abouelfab. If you’re looking to configure event tracking, we have a guide on the plugin website in relation to this:
https://sitekit.withgoogle.com/documentation/using-site-kit/event-tracking/

There are no configurations within Site Kit to define events such as adding an item to your cart. If you are having any issues with configuration within Analytics by following the guides on the page linked to above, you can reach out to the product experts at the Google Analytics Help Center.
