Conflicting declaration using SHT40 sensor with arduino opla MKR carrier

Question

I'm trying to use SHT40 this one with arduino opla kit, but I keep getting this error when compiling.

I already tried to rename every sensor_t to sensor_tmp in the SHT4 library

Code:

/*************************************************** 
  This is an example for the SHT4x Humidity & Temp Sensor

  Designed specifically to work with the SHT4x sensor from Adafruit
  ----> https://www.adafruit.com/products/4885

  These sensors use I2C to communicate, 2 pins are required to  
  interface

void loop() {
  sensors_event_t humidity, temp;
  
  uint32_t timestamp = millis();
  sht4.getEvent(&humidity, &temp);// populate temp and humidity objects with fresh data
  timestamp = millis() - timestamp;

  Serial.print("Temperature: "); Serial.print(temp.temperature); Serial.println(" degrees C");
  Serial.print("Humidity: "); Serial.print(humidity.relative_humidity); Serial.println("% rH");

  Serial.print("Read duration (ms): ");
  Serial.println(timestamp);

  delay(1000);

Thank you for any tips and help! :]
