How can i see on which button the users clicked

You cant' see what button the user clicked, unless you have the recording option (where you can see the click happening).

Hi Sabine, great question! You can see this under 'page views' in our Portal, if the button has a specific link. If your buttons don't have a specific link you can use our new Mouse Tracking feature to see which buttons were clicked. You can contact our Customer Success team for more information about this feature!
