Directly open FITS file from macOS in KStars

Perhaps it's already possible and I have something misconfigured but when I double click in macOS's Finder on a .fits file then KStars itself opens (configured that well) but doesn't open the FITS viewer with the selected file. Would that be possible to configure/setup?

Thanks for the great work and port (Stephane Lucas) to macOS!

Bye now,
