Not every light is supported — it depends on whether Zigbee2MQTT (or the underlying bridge) has a device handler for it. The list above is limited to lights confirmed to work with Zigbee2MQTT.
You need a Zigbee coordinator (USB stick) connected to Zigbee2MQTT. Once the coordinator is set up, you pair the light and it's controllable from Zigbee2MQTT.
