MQTT Autodiscovery Light with effects no effects shown

Hello,

I’ve written my own home automation system and want to control a rgbww LED Stripe with effects using HA- Autodiscovery.
Following JSON is in the config topic

{
  "dev": {
    "name": "Test ColorLED Effect",
    "model": "Controllino",
    "manufacturer": "phixom",
    "identifiers": "ctl_left"
  },
  "name": "Test ColorLED Effect",
  "unique_id": "1001_light",
  "state_topic": "homeassistant/light/controllino-test/1001/state",
  "command_topic": "homeassistant/light/controllino-test/1001/set",
  "brightness": true,
  "brightness_state_topic": "homeassistant/light/controllino-test/1001/brightness/state",
  "brightness_command_topic": "homeassistant/light/controllino-test/1001/brightness/set",
  "payload_on": "true",
  "payload_off": "false",
  "rgbww": true,
  "rgbww_command_topic": "homeassistant/light/controllino-test/1001/rgbww/set",
  "supported_color_modes ": [
    "rgbww",
    "effect",
    "brightness"
  ],
  "effect ": true,
  "effect_state_topic": "homeassistant/light/controllino-test/1001/effect/state",
  "effect_command_topic": "homeassistant/light/controllino-test/1001/effect/set",
  "effect_list ": [
    "ColorWheel1",
    "ColorWheel2",
    "Fade",
    "Random"
  ]
}

The LED is discovered. I can switch it on/off, doing dimming and setting colors. But there is no action item for selecting some of the effects. What is missing in the config or do I’ve to setup something in the HA gui?
