Anker PowerExpand 8-in-1 USB C Adapter - monitors not detected (Win10)

asus zenbook UX330uak, Win 10, attached AnkerPowerExpand 8 in 1 to USB-C port, connected hub to 2 monitors via HDMI - neither detected. I plugged, it refused to play. I want it to do what’s shown in the lovely image on this page. What am I missing?

Hope there is a user who got that hub and can give you an answer.
Unfortunately I can’t.
Otherwise you could contact the support.
