Floodlight wired ground

Hello,

I’m about to install a floodlight wired. I noticed on the instructions that it says to not screw the ground wire to the floodlight wired plate.

I have a plastic junction box, and there’s a ground wire, but no ground screw/hole in the box. What should I do? The lamp I’m replacing had the ground wire screwed to the plate.

Thanks!

Hi, i was wondering if you were able to install the lamp and if so what you did with the wiring? I called ring and they didnt know about this
