Decode rf remote signals with ESP32 or node MCU?

Question

I'm trying to decide my rf remote signals using ESP32 or node MCU. I have tried with Arduino and was successful but for some reason it is not working on either ESP32 or node MCU even using the same GPIO2 pin can anyone please tell me why both the boards are not able to decode the signal. I'm using the rc-switch library to decode and a 433Mhz transmitter reciever combo from amazon

RCSwitch mySwitch = RCSwitch();

void setup() {
  Serial.begin(9600);
  mySwitch.enableReceive(0);  // Receiver on interrupt 0 => that is pin #2
}

void loop() {
  if (mySwitch.available()) {
    output(mySwitch.getReceivedValue(), mySwitch.getReceivedBitlength(), mySwitch.getReceivedDelay(), mySwitch.getReceivedRawdata(),mySwitch.getReceivedProtocol());
    mySwitch.resetAvailable();
  }
}```

For ESP32, you should provide real GPIO number. For instance: mySwitch.enableReceive(13);

And without deep explanation, believe that it properly works with GPIO 13 and 27.
Details you can find by google...
