How to add scripts for udev to run

I have several scripts i would like udev to run when a monitor is plugged/unplugged. I have added the extra udev rules, but i don't know how to add the scripts that i want udev to run.

I have tried pointing udev to the scripts outside of nix with:

RUN+="/home/myUser/scriptName.sh"

This failed on rebuild with the error:

/home/myUser/scriptName.sh is called in udev rules but not installed by udev

So how do i install scripts by udev?

Do i have to create nix expressions for the scripts and install them with everything else?

Thanks.
