Improve typeform popup load speed using resource hints

I want to optimize our web page and came across an article which mentions resource hints.

These basically instruct the browser to pre-load new pages or scripts which you thing are necessary in the future.

I was wondering if there is a way to add a resource hint to my page, which would already load typeform before the user starts the form.
