Oled screen 0.66 inch doesn't work

I bought an Oled screen mini (0.66 inch 64x48 pixels) and I want to display "Hello World" on the screen.
I used Arduino Mega , I connected the pins of screen D1 -> SCL and D2 -> SDA and Rst -> 2,but the screen doesn't work or displays any thing (just black screen).
This is the code

#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
 

#define OLED_RESET 2  
Adafruit_SSD1306 display(OLED_RESET);
 
#define NUMFLAKES 10
#define XPOS 0
#define YPOS 1
#define DELTAY 2
 
 
#define LOGO16_GLCD_HEIGHT 16
#define LOGO16_GLCD_WIDTH  16
 
 
void setup()   {
  Serial.begin(9600);
 
  // by default, we'll generate the high voltage from the 3.3v line internally! (neat!)
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);  // initialize with the I2C addr 0x3C (for the 64x48)
  // init done
 
  display.display();
  delay(2000);
 
  // Clear the buffer.
  display.clearDisplay();
 
  // text display tests
  display.setTextSize(1);
  display.setTextColor(WHITE);
  display.setCursor(0,0);
  display.println("Hello, world!");
  display.display();
  delay(2000);
  display.clearDisplay();
 
}
 
 
void loop() {
 
}

This is the Link of my Oled screen from ebay:
