kde tablet mode keyboard

Hi,

     I am setting up a new framework12 tablet but I am having a problem 
finding a usable on-screen keyboard for tablet mode. Google is producing 
a lot of out of date information.  In order to get display rotation 
working I have moved to KDE from my preferred XFCE4 and my knowledge of 
KDE/Wayland/Plasma is limited.Ive tried plasma-keyboard which works but 
is missing the escape and function keys etc. so its not really usable.  
Everything else such as malitt and lomiri-keyboard seems to be qt5.  So 
... is there a better keyboard, or can I modify plasma-keyboard to add 
the missing keys, or can I mix qt5 (so I can try lomiri or malitt) and qt6?

I am not impressed with KDE so far (visually its great, but its 
documentation has been poor so far) so using another desktop is fine if 
I can get a viable tablet mode working.
