Importing ICC profiles

Hi!

I'm currently using Capture One 12.
I downloaded color profiles from Whitewall that I want to install in Capture One. 
I found this installation path on the internet:
Contents/Frameworks/AppCore.framework/Versions/A/Resources/Profiles/Input
The color profiles that are in this folder all have the extension ".icm", so Capture One cannot read the imported file and therefore cannot display it.
Question: What am I doing wrong?

Many greetings
