Floodlight Cam Plus Dusk Dawn Half Brightness Motion Full Brightness

I can seem to figure out how to get my new floodlight to act like my old one.My old one didn't have a camera but it would come on at night half power then when it detected motion it would go full brightness.I figured out how to get the floodlight plus to come on at night with the schedule. But I can't find a way for it to only come on at half brightness and then trigger full brightness with motionI found the brightness slider and that works to keep it at half brightness at night but then motion doesn't increase the brightness when triggered.I also purchased the light bridge but haven't installed it yet. Will that fix my issue?Or do these floodlights not work like regular led motion floodlights?
