MiLight configuration with new mqtt lights config

I’m using sidoh/esp8266_milight_hub successfully for years.
Old config was like this:

- platform: mqtt
  name: "TV Lamp"
  icon: mdi:television-ambient-light
  command_topic: milight/0x295A/rgb_cct/1
  state_topic: milight/states/0x295A/rgb_cct/1
  schema: json
  color_temp: true
  rgb: true
  brightness: true

How should new mqtt config look like?
I tried:

mqtt:
  light:
    - name: "TV Lamp"
      icon: mdi:television-ambient-light
      command_topic: milight/0x295A/rgb_cct/1
      state_topic: milight/states/0x295A/rgb_cct/1
      schema: json
      brightness: true
      color_mode: true

But it’s not working, light is not created.

Here it’s working without problem…
