[How to run or add keylogger]

Help, I made this keylogger software in which I want to make a Rubber Ducky Keylogger automatic. Is there anyway for me to make the duck run the keylogger or just simplycan anyone give a keylogger payload

P.S. I don't want the script to download some files and stuff just plain run

[Keylogger Usb Rubber Ducky]

Is there any way for me to inject a payload into the duck that records keystrokes automatically, or at least run a software that i made, a keylogger, automatically upon insertion?

If there is can you give the codes?

Thank you.
