WiFi isn't working because of a broken gold connector

I successfully fixed the screen on my old Samsung Galaxy S4, but there is another problem.

I’ve circled in red which small golden connector has been broken, is there any way to fix this connector or somehow get a replacement for it? It’s made the WiFi signal become extremely low unless I put pressure on it with my thumb, that is the only way the Wifi signal comes back.

It just seems like such a shame to have to completely stop using this phone because of one tiny little golden connector with such an important job. I’m sure that taking it to be done at any phone repair shop would cost more than another motherboard replacement anyway.
