Nintendo Switch LAN adapter does not work. What should I do?

I need help! I got the USB Lan adapter from UGREEN for 17 euro everything is connected correctly and I don't know what to do now?

If you go to Internet on the Nintendo Switch under System Settings there's Internet Settings there you go, there you can then select LAN connection if you click on it then it should work. Did you want to point out something at the top of the Amazon screenshot is something from your address etc.

Omg thanks but how do you delete this picture

You can delete it if you go to your question and click on the 3 dots on the side! Edit question! And then it should work.
