IoT Cloud - ESP8266 - LED wil not blink

Development Tools Cloud IoT

I have an ESP8266 attached to my mac.
The intention is very simple: I have a switch on the dashboard. If I put it 'on', the LED_BUILTIN should lit up, else it should go off.

Here is my code:

/*
 The following variables are automatically generated and updated when changes are made to the Thing
bool ledBtn;
*/

#include "thingProperties.h"
bool ledStatus = HIGH;
void setup() {
  // Initialize serial and wait for port to open:
  Serial.begin(9600);
  // This delay gives the chance to wait for a Serial Monitor without blocking if none is found
  delay(1500); 

  // Defined in thingProperties.h
  initProperties();
  pinMode(LED_BUILTIN, OUTPUT);
  // Connect to Arduino IoT Cloud
  ArduinoCloud.begin(ArduinoIoTPreferredConnection);
  
  setDebugMessageLevel(2);
  ArduinoCloud.printDebugInfo();
}

void loop() {
  ArduinoCloud.update();
}

/*
  Since LedBtn is READ_WRITE variable, onLedBtnChange() is
  executed every time a new value is received from IoT Cloud.
*/
void onLedBtnChange()  {
  // Add your code here to act upon LedBtn change
  if (ledBtn){
    ledStatus = HIGH;
  }else{
    ledStatus = LOW;
  }
  digitalWrite(LED_BUILTIN,ledStatus);
  Serial.println(ledStatus);
}

In my Dashboard I have a simple on/of button which is linked to ledBtn variable.

If I change the button, the serial monitor gives me the correct output (0 1 0 1 0 1, ...)

The LED_BUILTIN unfortionaly does nothing.
I tried a simular sketch in de desktop IDE and there it works (I used a timer instead of the Dashboardswitch.)
I get no errormesages .

Can someone help me with this? What am I not seeing here?

Solved!
Apparently my ESP8266 does not recognise

LED_BUILTIN

Instead I had to map the builtin LED to pin 2.
