Google Home can't control Shelly 2.5

Hi,
I've installed, successfully, Shelly 2.5 to control a roller/shutter (in Shelly App).
However, I'm not able to control it via Google Home.
I can see the device in the app (Google Home) but I can't send any command (up, down or anything else).
Anyone knows this issue?
Am I missing something? How can I put it to work?

Best regards,

Nuno Costa
