Pro micro (ATmega32U4 5V/16MHz) with resistive screen

Hello,
I would like to control resistive screen through the Pro micro. (4 wire : X+;Y+;X-,Y-)
I have already succeeded in print coordinates where I click on the touch screen in serial monitor but that's it...
I tried many possibilities and read this tutorial Turn your ProMicro into a USB Keyboard/Mouse - SparkFun Electronics without any luck...also this documentation about mouse function Mouse - Arduino Reference.

Here is my code for print coordinates in serial monitor :

4- Wire Touchscreen Connections

A1=====X-
A2=====Y+
A3=====Y-
=================================*/
//Define your Touch screen connections
#define X1 A0
#define X2 A1
#define Y1 A2
#define Y2 A3
//Define your screen resolution as per your Touch screen (Max: 1024)
#define Xresolution 1024 //128 //320 //1024
#define Yresolution 600 //64 //240 //600

void setup()
{
   Serial.begin(9600);
}

void loop()
{
  int X,Y; //Touch Coordinates are stored in X,Y variable
   pinMode(Y1,INPUT);
   pinMode(Y2,INPUT);  
   digitalWrite(Y2,LOW);
   pinMode(X1,OUTPUT);
   digitalWrite(X1,HIGH);
   pinMode(X2,OUTPUT);
   digitalWrite(X2,LOW);
   X = (analogRead(Y1))/(1024/Xresolution); //Reads X axis touch position
    
   pinMode(X1,INPUT);
   pinMode(X2,INPUT);
   digitalWrite(X2,LOW);
   pinMode(Y1,OUTPUT);
   digitalWrite(Y1,HIGH);
   pinMode(Y2,OUTPUT);
   digitalWrite(Y2,LOW);
   Y = (analogRead(X1))/(1024/Yresolution); //Reads Y axis touch position
  
  //Display X and Y on Serial Monitor
   Serial.print("X = ");  
   Serial.print(X);
   Serial.print(" Y = ");
   Serial.println(Y);
   delay(100);
