How to replace menu home back button sensor on samsung galaxy s4

[AC Question]

I recently replaced my cracked screen and messed up the sensor detecting the menu button which now does not function, has anyone replaced this or know how to do it?
The replacement part I need btw is called "Home Menu Return Sensor Flex Cable For Samsung Galaxy S4"

Offhand, I am not sure. Is there any teardown videos in YouTube?
