Using Webflow as a Teaching tool in a University Classroom

I am trying to use Webflow in an Interactive Design course that I am teaching this Spring at Villanova University. Webflow states that it is free for use in education but do my students still have to enter a credit card to get the free subscription? Is there a way around this?

I did speak with a person at webflow and was approved for the Growth account. Any help would be great appreciated.
