Translucent windows when dragging: missing setting

Hello! I am new to KDE Plasma and the forums, and I’ve been having an issue. In fact, this very account was created because I could not find an answer to it. How do I turn down the opacity of a window when it’s being dragged?
I searched through the Workspace behavior and Window management options and many more but no luck, I see no translucency setting. I was also unable to set a window rule that could detect when a window is being dragged. How can I turn on the feature? I am using the Breeze Dark theme.

System Settings > Workspace Behavior > Desktop Effects > Translucency

Sorry, it seems I am missing this option for some reason!

Ah, are you running in a VM?
