ESPHome ACS758 ESP32

Has anyone had the opportunity to measure the ACS758 current?

  - platform: adc
    id: "prad_silnikow_trackera"
    name: "Prąd Silników trackera ADC0"
    update_interval: 250 ms
#    unit_of_measurement: "A"
    pin: GPIO36
    filters:
      - median:
          window_size: 8
          send_every: 2
          send_first_at: 2
#    attenuation: auto 
#    accuracy_decimals: 3

I forget that ESP32 measures 0-1V, but I practically see no change in voltage
I found How To Measure Current Using XIAO ESP32 And ACS758 Sensor | A Step By Step Guide - Open Green Energy
and I don’t see any pullup resistor and the voltage is around 0.4V

The question is how to define it

const float VOLTAGE_REFERENCE = 3.3; // Change to 5 if using 5V VCC
const float SENSITIVITY = 0.04; // 40mV/A -Sensitivity of ACS758 (check the datasheet for your ACS758 model)
const float OFFSET_VOLT = VOLTAGE_REFERENCE / 2; // Zero-current output voltage ( Offset Voltage)
