Sharing an Office. Turn on "My" Lights

I share an office with my wife. She has her desk, I have mine. On/arround my desk I have some lights that I control in the Home app. Same with hers. I know that personalized requests are supported, so I was hoping to add the lights to a group, and name them Max's Lights. Same for her, a group named Amy's Lights. Then when one of us says "Turn on my lights" it turns on the correct group based on who asked.

Doesn't work. Did I set this up wrong? Overthinking it?
