KDE Plasma on Debian 13
I had a blocking program. I didn’t mind it closing, so I wanted to do that on shutdown. But I miss the button and clicked “Do not show again” in the popup that asks if you want to kill blocking programs.
I instead want that popup to remain. How can I restore it?

It’s very likely that it is in the graphical config somewhere, but why play “hunt the pixel” when you can get it in a few milliseconds (plus the time typing the grep command)?
