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?

from the top of my head there is a file ~/.config/dontaskagainrc that you can manually edit. I'm sure it's somewhere in the settings gui as well but no idea

Run this command

grep -ir ask ~/.config/k*

see if there is any relevant file/line or just past the output somewhere and provide a link

Wait, someone implemented a one-way feature in (presumably) kwin? How does that even make it to a stable release?

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)?

This post makes clear why I dislike such buttons. It's always unclear how to change the preference later.
