HID Keyboardkeyboard: Sendsend modifier keys only

I want to send modifier keys like shift, alt, ctrl, etc. without any other key. It should be theoraticalytheoretically possible due to the fact that it works for my normal keybaord.keyboard (Testedtested it with Xoutput and games).

For now I have to send dummy keystrokes like scroll lock (0xCF) to send the modifiers. I'm using https://github.com/espressif/arduino-esp32Arduino core for the ESP32 with the ESP32S3 Dev Module.

#include "USBHIDKeyboard.h" 
USBHIDKeyboard Keyboard;
Keyboard.press(KEY_LEFT_CTRL); Keyboard.write(0xCF); Keyboard.write(0xCF);
delay(1000);
Keyboard.releaerelease(KEY_LEFT_CTRL); Keyboard.write(0xCF); Keyboard.write(0xCF);

This works, but itsit's realy ugly,: sometimes the scroll lock LED flashes and in games the settings somtimes seessometimes see the scroll lock and complainscomplain.

Any ideas?
