Help identifying ripped cable on iPad screen (top edge)

Hello everyone,

I recently purchased a parted screen assembly on eBay, there is a ripped flex cable on this screen assembly located at the very top edge of the display assembly.

It is not one of the main display or digitizer cables, although the LCD has defects likely from heat, I’ve connected the screen and both the LCD and touch functions are still mostly functional, and these cable connects at the bottom of the screen... I believe this cable is also separate from the main Face ID and TrueDepth Camera assembly flex, as the repair guide shows them as separate assemblies.

The rip is on the thin flex that runs along the top of bezel, could anyone help me identify what does cable is and what function it serves?

Thank you all in advance,

Clippy
