How to install the LAMY Al-Star Pen Button Eraser Hack on the Remarkable 2

Hi, I need a programmer to help me install a hack into my remarkable 2 that will enable me to use the eraser function on a new stylus I purchased. There are instructions on this website, but I am no programmer and have tried a few times to no success. I was hoping someone might be able to spend a few minutes sharing screen and guide me through this process.

Thanks
Luke

Two options, I think I want to try the first as there are some added hacks.
