PLEASE HELP: Basic code to display a text with push button on arduino OLED i2c

I’ve looked all over the internet for libraries and sketches that will give me a very basic code to make the words
(“Hello world”) appear monetarily on an OLED i2c display when a push button is pressed and for it to disappear once the button is released. I’d build the code my self but I don’t have much knowledge to do so and dont have much time to learn. I have this code that works but its not simple enough to where I’d be able to modify it easy, adding in the words (“goodbye world”) that uses a separate second button.

Or if somebody could show me a code that could combine with this to also show the words (“Goodbye world”) with a separate push button, basically two-codes-in-one that shows different words with different buttons on the OLED i2c display :

#include <Adafruit_SPITFT_Macros.h>
#include <gfxfont.h>

// Adafruit_SSD1306 - Version: Latest

const byte buttonpin = 2;

const byte OLED_RESET = 4; // not used / nicht genutzt bei diesem Display
Adafruit_SSD1306 display(OLED_RESET);

void setup()
{
pinMode(13, OUTPUT);

pinMode(buttonpin, INPUT_PULLUP);
// initialize with the I2C addr 0x3C / mit I2C-Adresse 0x3c initialisieren
display.begin(SSD1306_SWITCHCAPVCC, 0x3c);

Serial.begin(9600);
display.clearDisplay();
display.display();
delay(2000);
display.clearDisplay();

display.setTextColor(INVERSE);
}

void loop()
{
if (digitalRead(buttonpin) == LOW)
{
display.clearDisplay();
display.setCursor(41,20);
display.setTextSize(1);
display.print("");
display.setCursor(32,20);
display.setTextSize(0);
display.print(“Hello World”);
}
else
{
display.clearDisplay();
}

display.display();
}
