missing metal cover for forward facing camera samsung S4 mini

I recently broke my screen and digitizer, decided to repair it myself, when taking the phone apart I realized my metal cover was missing that holds facing camera and proximity sensor in place. do I really need this and if so where can I buy it. the phone seemed to operate without it.
