ESP32 Onboard LED Not Blinking

[tomcat2900]

Hello !
I have a ESP32 BOARD DEVKIT V4 (ESP32-WROVER-IB (8 MB flash) ESP32-DEVKITC-VIB)
This code for blinking onboard LED doesnt work
/*

* ESP32 LED Blink Example
* Board ESP23 DEVKIT V1
*
* ON Board LED GPIO 2
*/

#define LED 2

void setup() {
// Set pin mode
pinMode(LED,OUTPUT);
}

void loop() {
delay(500);
digitalWrite(LED,HIGH);
delay(500);
digitalWrite(LED,LOW);
}

Can you tell me why ?
Thank You !

Because there is only one led on the board that that is for 5v power.
There is no user led.
