Drag-and-Drop FITS on Siril icon doesn't work

It is possible to open a FITS file in Siril by using the “Open” menu.
However Siril doesn’t recognise (and therefore doesn’t open) a FITS file by Drag-and-Drop.
An alert says : “The document … could not be opened. Siril cannot open files in the “Flexible Image Transport System document” format”
Siril 0.99.8.1 on macOS Mojave

So far drag and drop is only implemented in dev version.

Oh. And you are talking about drag and drop on icon. So a macOS stuff.
Seriously I even don’t know how it should work.
Sorry
