"Peek Desktop" button on taskbar

[Dave Close]

I recently installed a new machine, Fedora 41 and KDE. It's been a while
and I usually just upgrade. On the new machine, the KDE taskbar has a
button at the right edge which calls itself, "peek at desktop". It isn't
there on any of my upgraded machines, only on the new one.

I don't want it but I can't find a way to eliminate it. Searching finds
many descriptions of what it does, and some complaints about how it
works, but nothing about how to delete it. The general approach, right-
click and choose remove/delete or hover and choose the X, doesn't work
because those choices are not present. Searching system-settings finds
a setting to make it participate in button sorting (Window Management
-> Task Switcher) but that box is not checked. Some search returns
suggest that this button is a new "feature".

So how can I get rid of it permanently?
