Is there any way to be able to preview this on local?

[default5jq2gwz20zvz]

I'm unable to add localhost as a domain, and therefore I cannot review the presentation of PDF Embed until I push to production. Is there a way to overcome this?

Please try creating the credentials here: https://www.adobe.io/apis/documentcloud/dcsdk/gettingstarted.html

Pass localhost in the Application domain (without any path, port, query or fragment).

Hope this works! Please let us know if you face any issue.
