Remap mouse

I am using the install from here www.linuxcnc.org/testing-stretch-rtpreempt/.

I have added xinput and remap my mouse every boot with this command:
xinput set-button-map `xinput list | grep 'PixArt USB Optical Mouse' | grep -o [0-9][0-9]` 1 0 3

This works perfectly per session for me but can anyone give me heads up how to execute it automatically?
All I can find is old and inappropriate info via google mostly guiding me to outdated Ubuntu.

Sorted it by writing a bin/sh file and adding it to my start programs.
