How to hang the Fnatic LED sign light on the wall?

Hi guys! I got the Fnatic LED sign light and it comes with some accessories to what I believe is to hang it on a wall. However, having zero experience in this kind of DIY projects, I don't recognize these accessories nor do I know how to use them correctly.

Does somebody know how I'm supposed to hang the LED light on the wall, or have some video or something where the mechanism that I'm supposed to use is explained?

Thanks!!
