For someone ho might have the same question, I succedded with the following code

#include <RCSwitch.h>

RCSwitch mySwitch = RCSwitch();

int i;

void setup() {

  Serial.begin(9600);
  
  // Transmitter is connected to Arduino Pin #10  
  mySwitch.enableTransmit(10);

  // Optional set pulse length.
  mySwitch.setPulseLength(355);
  
  // Optional set protocol (default is 1, will work for most outlets)
  mySwitch.setProtocol(1);  

}

void loop() {
 
  i = 0;

  while (i < 10)  {
    mySwitch.send(6249743, 24); //buttonA
    //mySwitch.send(6249742, 24); //buttonB
    //mySwitch.send(6249741, 24); //buttonC
    //mySwitch.send(6249740, 24); //buttonD
    
    i++;
    delay(400);
  }

  delay(3000);
}
