Playing Euro Truck Simulator 2 with the Thrustmaster T300 RS GT Edition?

Can someone tell me how I can play Euro Truck Simulator 2 with the Thrustmaster T300 RS GT Edition steering wheel?

I have already seen a few on Youtube and Twitch who have the same steering wheel, and play ETS2 with it. But it doesn't work for me and I can't find a video on how I can set it up.

For many other steering wheels yes, there's no setting video for the GT Edition.

Do you have any ideas?
