Broken volume connection after 'GPS fix'

After trying the famous GPS fix on my LG G5, I have snapped off one of the three small golden connectors that are actually for the volume rocker buttons.

What the !&&* do I do now?! It came loose while the phone was closed, so I have no idea where it's gone. Can you buy these parts? can I re-create a new one? I don't have any of the tools needed, so I soppose I'd need to buy the right things too?

Any further help with what I need to buy to actually fix the GPS issues would be great
