An example Hubspot form embed - top won't work in Statamic, bottom will. Seems like it must be minified.

hubspot-form-example-min.js

hbspt.forms.create({portalId:"1695915",formId:"c5cbd91e-27da-4cb2-8bee-7ef37300c145",goToWebinarWebinarKey:"7245946950768380939",target:"#hsFormContainer",onFormSubmit:function(e){window.dataLayer=window.dataLayer||[],window.dataLayer.push({event:"GAEvent",eventCategory:"Webinar - See CCMS Live",eventAction:"Form Submission",eventLabel:"Registration",eventValue:"2"})},css:""});
