Hi OP I purchased this LED light on Amazon and plugged it into the rear USB C port in the console below the air vent. It lights up the back seat area nicely

⚠️Warning, it breaks easily if bumped so I can’t say it is a perfect solution.

So I also purchased the Abstract Ocean rear floor well lighting kit: https://abstractocean.com/products/m3y-premium-rear-footwell-lights

The foot well lighting kit will eventually replace the USB C LED light when I get a chance to install it.
