Hello Sam,
Thanks for writing in!
Regretfully the classic list icon element cannot be used to display the recent post items in your page. The only element we have is the Classic Recent Posts element that you can use. You may use the WP Recent Posts widget instead. To do that, you can do the following:
1.) Go to Appearance > Sidebars and create a custom sidebar
2.) Go to Appearance > Widgets and insert a WP Recent Posts widget into the newly created sidebar area.
3.) Please edit your Support page and then insert a Widget area as a replacement for the classic list icon. With the Widget Area element, you can select the newly created sidebar to display the WP Recent Posts widget.
Hope this helps.
