How to embed Webflow site with custom domain into an iframe

Hi,
I’m trying to embed my webflow page into another tool I’m using via an iframe.

Here’s the custom HTML I’m trying to use:

<iframe src="https://www.shopfor.co.nz/untitled" title="Shopfor"></iframe>

Unfortunately, I’m getting the following error:

Refused to frame 'https://www.shopfor.co.nz/' because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self'".

I’m assuming this is a configuration thing on the Webflow end? I’ve read about this not being possible on the .webflow.io domains but no clear guide on how to achieve this on a custom domain.

Can anyone help?

Thanks!

I have the same problem. Clear guidance with regards to the integration of a custom domain would be really appreciated.

Thanks!
