Using Google Assistant with multiple bulbs

I’m trying to figure out how to set up my bulbs (one white, one color) using Google Assistant.

I have “Yeelight” connected to Google Assistant, but can’t get any commands set up; it just shows me to open the Yeelight app.

Shouldn’t it be possible to select which bulbs (and which room) should turn on and for the color bulb, to say what color or scene?

you sould first add the bulbs and scenes in yeelight app and then link it to google assistant so it can see it.
