Filament sensor for ender 3 v2 NEO

Does anyone know if such a sensor exists and if so where can it be purchased?



It sounds like a bit of hard work according to this reddit post:-

yes indeed. So if I understand it correctly it requires another firmware in order to work. I suppose that, if firmware is upgraded the normal filament sensor for the ender 3 v2 can be used and installation instructions are the same for the NEO ?
