XS MAX Flexcables cut off - replaceable?

Hi all,

I tried to replace my display on an old XS Max. Unfortunately, I broke 2 flex cables... (marked with green arrows on the photo).

I understand the lower one is that of the FaceID/Front camera. Can I replace that one, is that possible?

Also, what is the upper flex cable that I broke as well and can I replace it as well?

Phone boots up (I gotta say, the display is really, really, bad)...

Kind regards and thank you!
