The Addons tab on DXP ToolKit's settings page gives you the option to connect DXP ToolKit with your analytics engine.
DXP ToolKit currently integrates with Matomo Analytics as well as Google Analytics V4.
In order to connect to either of these services, you only need to select the relevant checkbox and click on the Enable / Disable Addons button.
Please note that for the Google Analytics V4 integration you will need an active and correctly configured instance of the Google Site Kit plugin.
Comparatively, for the Matomo Analytics integration you will need an active and correctly configured instance of the Matomo Analytics plugin.
