Using a Windows keyboard. How can I map the "Print Screen" button to open Flameshot and take a screenshot?

I installed https://flameshot.org/docs/guide/key-bindings/#macos and want to use that when I take screenshots. I'm using a Logitech USB wireless Windows-style keyboard, so I have a Print Screen key. When I press the Print Screen key, I want Flameshot to take a screenshot. At first, I thought I'd be able to map it within Flameshot > Configuration. When I try, it treats Print Screen as F13. Pressing Print Screen still doesn't seem to take a screenshot, though.
