You don't need to do anything for this, it works OOTB and collects data and shows it on the
Experience Analytics dashboard.
There could be many reasons for analytics data not showing, there is a knowledge base article that describes the processes for troubleshooting the most frequent issues with
Analytics data in the
Sitecore Experience Database installation.
You need to run a few pages on the browser of the newly created site and it will start collecting the data and show it on the
Experience Analytics dashboard. It may take a couple of minutes to show the data.
So create a few pages and run them and it will start collecting the data if everything works perfectly with your
Sitecore instance. Otherwise, follow the above article to troubleshoot the issues and correct them.
Finally, I would say, if it still does not work then you can check logs and get some context to find out the actual error coming with your Sitecore solution.
Hope this information helps you to start.
