Did a screen replacement and now I have no WiFi and very bad Bluetooth

So as the title says, I performed a screen replacement on my watch (S4 44mm) and it works but now my WiFi never shows any networks and the Bluetooth connection is extremely poor (watch will disconnect if I have phone in my pocket and watch on wrist on table, it’s that bad).

i was looking around inside and comparing with the tear down to see what I could have damaged or forgotten to put back, and the only thing I noticed that was missing was this:

Then I remembered that when removing the display, that little gold thing popped off and flew across the room so who knows where it is now. Anything I could use to replace it? Since I’m pretty sure that connects with a little metal tab on the screen to provide wireless functions
