Emulate the R key on a Mac keyboard

[foufouner1977]

Hello,
I would like to emulate the R key on a Mac keyboard using a button and an M5StickC PLUS2 ESP32.

I asked my friend ChatGPT how to do it and this is what he told me

I connected my M5StickC PLUS2 via USB to my Mac to connect it to my Arduino IDE.

Only if I bring the code that ChatGPT generated for me.
Any ideas?

Ok so if I try with my code

#include <M5StickCPlus2.h>
#include <BleKeyboard.h>

BleKeyboard bleKeyboard("M5StickC_Keyboard", "M5Stack", 100);

void setup() {
  M5.begin();
  Serial.begin(115200);

  bleKeyboard.begin();
  Serial.println("En attente de connexion Bluetooth...");
}

void loop() {
  M5.update();

  if (bleKeyboard.isConnected()) {
    // Si on appuie sur le bouton A du M5StickC
    if (M5.BtnA.wasPressed()) {
      Serial.println("Touche R envoyée !");
      bleKeyboard.press('r');
      delay(100);
      bleKeyboard.releaseAll();
    }
  }

  delay(10);
}

I have this error message
