Wiring Aeon Labs Micro Switch G2 Directly in Light Box

Got used to putting these little guys behind the switches while re-setting up my ST at my new place. Ran into a closet though where the power is in the light box. Don’t recall how I did this at the last house, so I’m hoping you guys can provide an assist here. While there are two light bulbs in the fixture, it’s on a single switch. So nothing fancy…just different from what I’m used to seeing. Here’s a picture of what I see. Trying to figure out what goes where.

Any help/guidance is appreciated.
