Yeelight Smart Curtain - Google Home Routines

Hi, does anyone know if google home routines can be created with yeelight smart curtain controller? In the google home app, I see yeelight lights (devices) available when I create routines but the curtain motor does not appear as a device.

Similarly, in the yeelight app, i only see that yeelight lights can be added to a scene. I am unable to add the curtain motor to a scene.

Anyone knows if adding curtain controller to yeelight scene or google home routine is possible?
