how to disable single click to open files/programs in Kubuntu?

I just upgraded to Kubuntu 20 and I noticed that just clicking once on an icon opens it, which is quite annoying. Is there a way to change that to double click like it should be?

Everything I find in my search tells me to go to system settings, input devices, and mouse but I don't see any option there for that. I also don't see any options anywhere within Dolphin itself.
