Purpose of X933422-005 Cable?

Hello,

I am working on repairing an old Surface Pro 4, and during the process unfortunately destroyed the X933422-005 flex cable/antenna that is mounted in the top bracket of the device. Here is a link to an example of the part. Mine does look slightly different, as it says "UFK 5115 152 X933422-005" on it. I have also circled the part in the below image.

I am trying to decide if I need to perform some more aggressive repairs, in an attempt to replace that part, or if I can simply live without it. It looks like some sort of antenna, but Bluetooth and Wi-Fi seem to be working, so I am not sure what it's purpose could be.

Thanks!
