Heated Rear Seats

Hello NX Community,
I recently purchased a 2021 300h base and was going through all the different things that it offers. It's a pretty impressive arsenal of technology and features.
However, I was wondering about rear heated seats and whether they can be added or not. I know that Lexus offered it as an option so I am curious if anyone has ever tried adding this feature.
I took off the rear panel of the center console and the wiring for the heated seat switch is there. Also, according to the wire routing manual, the fuses for the heated seats are located in the truck near the battery and they are all in place.

So it makes me wonder, is the switch all I need to have rear heated seats?

If anyone has any knowledge or experiance they would like to share, I would greaty appreciate it!
