Where do I get replacement for Steam Deck Wi-Fi module antenna cables

Hello,

When I tried to operate on my Steam Deck, I accidently cut one of the two Wi-fi small antenna cables (which has the gold-colored connector head). Can someone please help to confirm whether this cable can be replaced and where can I get it? I couldn't find any replacement guide and the cable is not sold on the iFixit site. Thank you in advance for your help!
