Guidance requested for installing Camera & Sensor Cable Shield Sticker

After my first "fail" in repairing an iPhone, I'm starting over, with new parts. In addition to a new front panel (I tore a cable on the "old" new front panel), I also ordered a new Camera and Sensor Cable Shield Sticker to replace the original one which looked pretty worn out after having been removed and replaced at least twice.

After reviewing assorted how-to guides, I've yet to find one which details how to go about replacing this part. I'm planning on just figuring it out as I go along, but I'd sincerely appreciate it if others would share their experience/advice. (I'm really hoping to avoid future problems with this project!)

Thanks in advance for sharing your knowledge.
