Preview url

If i want to preview a working TinyMCE field what domain do I add to my TinyMCE appoved domains as I need to set api key and approved domains? v0.app doesnt work?

The preview iframe is currently using lite.vusercontent.net however this is not documented and may not remain this way forever

If you right click on the preview and View Iframe Src it will take you to the direct URL for that preview

Ok thanks.
Feature request: have that preview URL easily available to users in an info section someplace. Its handy for 3rd party apps, like Google maps too, that require domains to whitelist.
