In case this is relevant for you as mi e is a 2017 35T . I purchased an aftermarket Kurt Trailer Hitch from etrailer for $227 and fitted it myself. I did not need the wiring as I only use it for carrying bikes.
I saved a bunch on the Jaguar hitch which the dealer would have fitted for me.
However, Warning ...fitting was a pain in the arse! You have to remove the rear bumper and then fit it behind the steel strengthening crossbrace which unbolts. Took me 3 hrs.
The OEM jaguar solution is definitely more elegant and doesn’t stick out as much if you want to pay the $$$$$.
