Importing screenshot keyboard shortcuts

Trying to setup keyboard shortcuts for Flameshot. (
They provide a file to allow import of standard shortcuts, but can’t seem to get it working. Have tried Shortcuts > Import Scheme, and Add Application/Add Command, but none seem to do anything…?
Think KDE may have changed the system since the Flameshot file was created…

This might help

Unfortunately, no longer works.
Custom shortcuts aren’t really a thing in KDE/Plasma any more…
VERY disappointing.
