RGB lightbulb shows only switch

Hello, i bought a ZigBee RGB light bulb from ali. They advertise the ability to change color temperature and brightness.

I have received the bulb and connected to mains. Paired it with home assistant no problem (SonOff dongle), i went to check which entities it shows and only found 1. “light”. So i can only turn on or off the light and nothing more.

Do i have to do some manual configuration before i can use the other functions? Or did they advertise fake functions.
