What am I doing wrong with chrome?

I got chrome done at the salon and a day later I messed up my thumb nail on my left hand 🙃 so I thought “oh fun let me get some chrome powder and fix it myself” but other than the color not being an exact match, I cannot for the life of me get that same mirror shine effect. I took the gel off and redid it maybe 3 times and it still looks just like a metallic nail polish. I used a clean applicator and tried varying curing times and it keeps coming out the same. I can’t figure out what I’m doing wrong. Any advice?? Thank you!!
