I found this a very useful tutorial however I had to modify the last few lines since wait() function used an integer which was not able to hold the 60000 specified.

My changes:

 // Wait 60 seconds until next update
  wait(60);
    
}

// Wait for a given time using the watchdog
void wait(int total_delay) {
  
  int number_steps = (int)(total_delay/5);
  wdt_enable(WDTO_8S);
  for (int i = 0; i < number_steps; i++){
    Serial.println (F("Waiting for 5 seconds ..."));
    delay(5000);
    wdt_reset();
  }
  wdt_disable();
}
