Could someone explain how to use new color management in Windows?

I'm really not an expert on this, but as far as I understand the  "color management profile" should be saved in some ICC file. In GIMP for example you have an option to load ICC profile from the file on the disk, but there is no such option in Inkscape. At least not in Windows build. So where the profile is suppose to be taken from?

Thanks for the explanation :)

Best regards,
