Shortcuts to take Live Photos hands free with Siri on iPhone 11 Pro Max

I am photographing objects held in my left hand with my right hand on a horizontal plane. The shortcut Say Cheese makes this possible without having to click.

Since I can not see a preview, taking a Live Photo would be better. I have tried changing the variable to save from “Photo” to “Live” and “Live Photo”, but it seems it is the first expression you have to change.

I wonder if any of you know how to do that?
