Automation MQTT - action using IF, ELSE

Configuration

Hi guys, could somebody help me with writing automation for MQTT trigger.
I want to turn ON or OFF switch depending on received payload. I did that for each payload, but would like to use only one automation for one switch and use IF, ELSE, END IF. Tried a lot, but without success…
This is what I have tried for Action when deleted payload from trigger (using yaml) and below is two working automations:

service: switch.turn_on
data:
  value: |
    {% if is_state ('trigger.payload', 'ON') %}
        turn_on:
          service: switch.turn_on
          target:
            entity_id: switch.doser_active
    {% else %}
         turn_off:
           service: switch.turn_off
           target:
              entity_id: switch.doser_active
     {% endif %}

working automations (copied from automations.yaml)

- id: '1622358858743'
  alias: Aquaponics Doser Active ON MQTT
  description: ''
  trigger:
  - platform: mqtt
    topic: aquaponics/turnOn
    payload: 'ON'
  condition: []
  action:
  - service: switch.turn_on
    target:
      entity_id: switch.doser_active
  mode: single
- id: '1622405410615'
  alias: Aquaponics Doser Active OFF MQTT
  description: ''
  trigger:
  - platform: mqtt
    topic: aquaponics/turnOn
    payload: 'OFF'
  condition: []
  action:
  - service: switch.turn_off
    target:
      entity_id: switch.doser_active
  mode: single

and this did not help also

service: |
  {% if ('{{ trigger.payload }}'), "ON" %}
    switch.turn_on
  {% else %}
    switch.turn_off
  {% endif %}
entity_id: switch.doser_active

You want the choose option, which is exactly what you’re looking for.

Thank you very much !
Finally this is working:

choose:
  - conditions:
      - condition: template
        value_template: '{{ trigger.payload == "ON" }}'
    sequence:
      - service: switch.turn_on
        target:
          entity_id: switch.doser_active
default:
  - choose:
      - conditions:
          - condition: template
            value_template: '{{ trigger.payload == "OFF" }}'
        sequence:
          - service: switch.turn_off
            target:
              entity_id: switch.doser_active
    default: []

You could do it like you expected but the syntax of the service call was wrong.

This should work:

service: |
  {% if  trigger.payload == "ON" %}
    switch.turn_on
  {% else %}
    switch.turn_off
  {% endif %}
entity_id: switch.doser_active
