How the heck do I access the File Upload question type form the NEW Builder?

I joined Typeform about a month ago, and have only ever had the New builder.

Have upgraded to Essentials plan in order to gain access to the File Upload question type for our customer feedback form (we are a tech company)

I can’t figure out HOW to access the File upload question in the new Builder.

Alternately, I’d probably be fine using the Classic builder to build a form so long as I get access to that question type, but so far as I can tell there’s no way to access the Classic builder with my new-ish account.

Help?
