Turning on/off oled after 7 seconds

Hello, I wanted to be able to turn on the oled display ONLY when I push the button, then have it turn off after 7 seconds and not having the display on all the time. It will display "Door open" constantly and I wanted it to display for 7 seconds. What do I need to put in the code to do this?

#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define OLED_RESET     4 // Reset pin # (or -1 if sharing Arduino reset pin)
Adafruit_SSD1306 display(OLED_RESET);

#define pushButtonPin 8
int buttonPushed = 0;

void setup()
{
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
  display.clearDisplay();

 pinMode(pushButtonPin, INPUT_PULLUP);

void loop()
{
if (digitalRead(pushButtonPin) == LOW) {
    buttonPushed = 1;
  }
  if ( buttonPushed ) {
    
        display.setTextSize(2);
  display.setTextColor(WHITE);
  display.setCursor(0,0);
  display.println("Door open come in!");
  display.display();
  
    delay(7500);
   
    buttonPushed = 0;

}
}

How about a clearDisplay()?

Got it! It seemed to work when I added this at the beginning of the loop
Thanks!!!

display.setTextSize(2);
  display.setTextColor(WHITE);
  display.setCursor(0,0);
  
  display.display();
  display.clearDisplay();
