Joystick library 2.0

Hello,
I'm trying to get this to work: https://www.instructables.com/id/Arduino-LeonardoMicro-as-Game-ControllerJoystick/

I don't understand step 7: "While this dialog has focus, ground pin A0 on the Arduino to activate the test script. [...]"

Anyone please?

Use a wire to Connect A0 to GND on the Arduino.

Thanks for reply, I did it and it all the buttons and axes started activating and moving on their own but still doesn't work. I can't understand that guide. What am i missing? I think i have to learn all the coding to understand this.

Explain exactly what you mean by "still doesn't work".

The game device detected by windows doesnt actually respond to any input from the thumb joystick
