I lifted the silver circle pad (as you can see on this picture

I read something to solder a copper wire to the pin of the switch on one end and the other end to the metal that the the silver circle was connected to.
Can someone tell me where I should solder the other end of the wire?
Here are two pictures of the current status:

Please ignore the soldering, I know it's miserable and I'm going to desolder/solder it better and practice a lot more before I finish this project..
As you can see I already soldered a wire to the pin, I just need to know where I need to solder that wire..
It was a lot of work for me as a solder noob and I really want to save this PCB and escape key.
I really hope that you can help me out!
Best Regards
