We have a Creator form that I want to only be embedded on approved sites. It looks like you can do this easily in Zoho Forms (here) but I'm not seeing a way to do it in Creator. We have had this set up for a long time, and it would be cumbersome to change to Forms, so I'm trying to keep it in Creator if possible.

For example, I want to allow the Creator form to be embedded on google.com but not apple.com. How can I do this?
