Debian12 with KDE5: How to make Wayland the default?

I thought it was enough to Log Out then in the upper left of the lockscreen clicking the dropdown to change it from "Plasma (X11)" to "Plasma (Wayland)" would be enough but apparently it isn't. I checked if I was using Wayland with loginctl show-session 1 -p Type (replace "1" with your session number shown by running loginctl) after a reboot and it showed X11.
