The Refocus tool (Sharpen) is missing in 8.8.0 (Flatpack/Wayland)

I have found a recent (18/Oct/2025) bug report on bugs.kde.org against 
DK 8.8.0
https://bugs.kde.org/show_bug.cgi?id=510760
where someone reports that build system struggles to include Eigen 
library, which supposedly will prevent refocus from being compiled in...

But then I am using flatpack not building the DK myself...

Any advice would be appreciated,
