macOS and SU 2020: How to make the Finder show Sketchup Files via QuickLook?

on my mac

SketchUpQL.qlgenerator v3 from SU v19 works but
SketchUpQL.qlgenerator v4 from SU v20 fails…

# renaming the folder
/Applications/SketchUp 2020/SketchUp.app/Contents/Library/QuickLook
# to 
/Applications/SketchUp 2020/SketchUp.app/Contents/Library/QuickLook!

and restarting the mac seems to fix it…
