CMYK color mode Gimp 2.10

[Jānis]

If I run Cyan as a standalone, it will find all the colour profiles (in "/usr/share/color/icc").

However, if I use the GIMP 2.10 integration and click "Cyan -> Export Image", there are only two built-in CMYK profiles available (and one RGB). So, I cannot select the one I actually need.

Can someone tell me how to make Cyan see the other color profiles?

And I need the integration mode, not standalone, because the standalone Cyan does not open my XCF file properly, while exporting from GIMP seems to work all right.
