Digikam ignores sidecar info from Darktable

[Willem Ferguson]

I am a new user of Digikam, doing most of my image manipulation in 
Darktable. As currently set up on my machine, the dk V5.6.0. AppImage 
does not see the the Darktable sidecar files: the Darktable EXIF data 
and image changes (e.g. cropping or contrast) are not shown when viewing 
Canon CR2 files in Digikam. Is there a way of achieving this?

Kind regards,

Willem Ferguson
