IKEA Tradfri Select Color from Dashboard?

I am running Zigbee2MQTT via a ConBee2.

I have setup my first batch of IKEA Tradfri LED1923R5 (with RGB color) devices and can turn them off and on.

How can I add RBG colour control to the dashboard?

Also, how do I perform the OTA update?

Thank you

Color: Take look on more info popup when light is on, you will see pick color wheel.
OTA: Take look on zigbee2mqtt gui.
