Project mention: ESP32-BLE-Keyboard Example - "does not name a type" error | /r/arduino | 2023-10-24

I am trying to get started with the bluetooth keyboard example for ESP32. using the example, it throws the error: "Compilation error: 'BleKeyboard' does not name a type" I have tried to compile this in Arduino 1.8 and 2.2.1 and on multiple computers. all fail to compile. I even tried to downgrade the ESP32 package to 2.x to no avail. What am i missing here?
