Ambient sensor(r) damaged can it be repaired

So while disassembling the sensor cable from the screen the ambient sensor was damaged and came off from the cable at the back. The separation seems clean like it was held only by adhesive and not soldered. Can it be simply tacked back on while aligning the contacts and be functional. Or is it unrepairable; if unrepairable do I lose aurobrightness and trutone or can one sensor suffice?

final question is does this affect anything else about the FaceID functionality? Thank you
