Lego 2K Drive (Cartridge version) for Nintendo Switch

For the Nintendo Switch, is there actually a cartridge in the box? I've seen so many reviews elsewhere saying that it's just a box with code inside.

is it a physical or a code ?

Is this a code in a box or physical? because I thought it only came with a code but this says cartridge

Is there an actual cartridge in the box or is it just a digital download game?
