I got one of these: https://www.amazon.com/gp/product/B073XGXNJY/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

I hollowed out some foam from the bottom and strapped that on top of the existing armrest. It hangs off the front enough to cover the rear cup holder but leaves the front onee usable. That allows me to comfortably put my elbow on it and have my hand on the wheel.

So I ordered this one :
