How to tell Digikam I want raw files opened with Darktable?

Hi Mica-

I ran across this old thread, and wonder where these commands might go.

For digikam to launch darktable, something like flatpak-spawn flatpak run org.darktable.Darktable <file name>

I have a Flatpak install of DK and DT on a laptop, and in DK, the settings for the image editor doesn’t see any external editors (they are greyed out). On my desktop pc, they are available in the non-flatpak installs I have configured.

Any hope to get the two flatpaks working on the laptop? It’s an immutable distro, so not sure of alternative means.

Thanks,
