Downtube storage cover’s name?

Hi everyone, I just received my first Canyon bike which is a Grizl CF 6. Love the bike, great joy to ride, but I've managed to lose the plastic cover for the downtube storage compartment (together with the 6+1 multitool that was in it 😀 ) on my very first ride, got so excited I didn't check if the lid was closed correctly.

Now I'm looking for help since I couldn't find the exact name of that plastic part and if its possible to get a new one from Canyon, or is there like a 3d printable somewhere for it?
