Help with Keyboard.h

I need help I can’t use Keyboard.write() here is my code

#include <HID.h>
#include <Keyboard.h>




void setup() {
  // put your setup code here, to run once:
  //Setting up Digital Pins
pinMode(2, INPUT);
pinMode(3, INPUT);
pinMode(4, INPUT);
pinMode(5, INPUT);
pinMode(6, INPUT);
pinMode(7, INPUT);
pinMode(8, INPUT);
pinMode(9, INPUT);
pinMode(10, INPUT);
pinMode(11, INPUT);
pinMode(12, INPUT);
pinMode(13, INPUT);
// setting up Analog Pins to Digital
pinMode(A0,INPUT);
pinMode(A1,INPUT);
pinMode(A2,INPUT);
pinMode(A3,INPUT);
pinMode(A4,INPUT);
pinMode(A5,INPUT);
Keyboard.begin();

}

void loop() {
  // put your main code here, to run repeatedly:

  if (digitalRead(13) == LOW) {Keyboard.write(113);}

}

Keyboard.end();

here is the error output

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

You can't use the keyboard library on an Uno, only on boards with native USB like Micro and Leonardo.

OK got that!
