Settings for custom Color Profiling Capture One Pro 21 / Need updated info

The new "canned" camera color profiles in C1 v21 look pretty good. However it would be really helpful to have either support documentation, or videos available which would clearly state how to set up Capture One for making custom profiles in Applications like BasICColor, X-Rite etc. There's readily available information on this subject for C1 Cultural Heritage edition, but what about those of us using Sony, Canon, Nikon etc. with C1 or CV1 Pro?

On the Capture One web site, al of the tutorials and documentation for this subject are ancient.
