Emulate the R key on a Mac keyboard

[Step72]

I'd like to emulate the R key on a Mac keyboard using a button and an M5StickC PLUS2 ESP32 with Arduino.

I asked my friend ChatGPT how to do it, and here's what he told me.

So I installed all the necessary libraries.
ESP32-BLE-Keyboard

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

I then transferred my code from Arduino to my board, but I have this error!

grpc: error while marshaling: string field contains invalid UTF-8

Compilation error: grpc: error while marshaling: string field contains invalid UTF-8`

It seems to be coming from the BleKeyboard library.

Do you have any ideas or solutions to help me emulate the R key on a Mac keyboard with an M5StickC PLUS2?
