EndLine Switch to Motion Sensor - No Neutral

I have a Leviton DOS02-LW Motion Sensor Light Switch. I'm trying to put it on an end-line switch (only one wire goes into box). There is no common wire, but the description says it shouldn't need it.

Per instructions, I should be taking the green ground + the common/white/green-sleeved wire and attach it to the ground, and the neutral and hot can be put on either to the bulb wire.

It doesn't work though - no motion sensor or switch working, and the seems to have electricity in it now, which seems like a huge red flag (not keeping it hooked up while posting this.)

Can you install a Motion Sensor on an endline switch? (This switch is old work prior to me owning the home - I hate endline switches)
