Help for showing multi text via botton in ssd1306 display

Unfortunately, I do not know much about Ardiono coding
And I could only write code here

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

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 32 // OLED display height, in pixels



// this constant won't change:
const int  buttonPin = 2;    // the pin that the pushbutton is attached to
const int ledPin = 13;       // the pin that the LED is attached to

const byte OLED_RESET = 4; // not used / nicht genutzt bei diesem Display

Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);


// Variables will change:
int buttonPushCounter = 0;   // counter for the number of button presses
int buttonState = 0;         // current state of the button
int lastButtonState = 0;     // previous state of the button

void setup() {
  // initialize the button pin as a input:
  pinMode(buttonPin, INPUT);
  // initialize the LED as an output:
  pinMode(ledPin, OUTPUT);
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C); //Start the OLED display
 
  display.clearDisplay(); 
  display.display();
  display.setTextSize(2);
  display.setTextColor(WHITE);
  display.setCursor(30,0);
  display.println("WELCOME");
  display.display();
}


void loop() {
 
}
