How to install older model Intuos 5 Wacom tablet on new M4 iMac with no pass key?

I have a Wacom Intuos 5 tablet (PTH-850) that didn't need a passkey when I installed it in my 2017 iMac. I need to install it in my new M4 iMac, but don't know the exact process or if I need a passkey or not. When I went to register the tablet at Wacom (in preparation for the new install), It asked for the model and then the passkey in order to register. I need help on the install (obviously I will need new drivers for the new computer, but that is about all I know). Any help would be welcome.

Thanks, Scott
