Can't find CE Number on DJI Tello Drone

I got a Tello Drone and live in Switzerland. Here, almost the same drone rules apply as in the EU, including the CE Number Rule. I want to fly it legally, mainly so my insurance will cover any damages in the (unlikely) case of an accident.

The problem is, I can’t seem to find the CE Number on any part of the drone or packaging. I even pried off the white top cover, underneath which all the regulatory info is written, but I can’t seem to find the logo anywhere.

Can anybody give me a hint where to find it? I am worried, I got a drone without the number, in which case I can’t fly it. (Purchased on Amazon DE, in case it helps)
