Recent Global Posts Widget

Hi,
I have installed and activated the "Recent Global Posts Widget" https://www.screencast.com/t/EjVVSht9VT

The plan are to show latest post from the Multi sites WP on the frontpage of brygblog.dk - It is no where here to pick https://www.screencast.com/t/m3yIvtDJ

What do I do wrong ?
