Color control is not possible when adding Lighting Matter Device

Hi, I compiled the example source of Matter’s lighting below using the ESP32-C3 development board and connected it to both the SmartThings Hub and SmartThings Station, and it was added as a Matter Device, but I couldn’t control the color of RGB LEDs on the development board, just the brightness and on/off as shown below.

As shown in the video below, when I connected to Apple HomeKit, I could control the color in HomeKit. Is it because SmartThings is still working on Matter? Or I wonder what kind of work is needed.

Did you try to touch green button?

The green dot is an icon that shows the displayed reflash status by capturing the screen while reflashing the screen. Sorry for the confusion.

The SmartThings drivers certainly seem to support colour control. Whether they are ahead of the backend I wouldn’t know.
