How do I build an audience for visitors with a high 6sense intent score?

Our team runs 6sense and I want to surface a stronger offer only to accounts that are actually showing buying intent, not to everyone who lands on the site. The idea is to reserve the high-commitment CTA for the accounts most likely to convert.

How do I express a high intent score as a Croct audience? I understand the concept of audiences but I am not sure how the 6sense score gets into one, or what has to be in place for that data to be available.
