Zoho Sign URL cannot be embedded in an iframe on the React side.

Zoho Sign URL cannot be embedded in an iframe on the React side.

The Zoho Sign URL cannot be embedded inside an iframe within a React application (or any web application) because Zoho enforces a Content Security Policy (CSP) that explicitly prevents iframe embedding from external origins. When attempting to load the Zoho Sign page in an iframe, the browser blocks it and displays the following error:

Refused to frame 'https://sign.zoho.in/' because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self' https://sign.zoho.in".

Can you provide an alternative to using the Zoho Sign URL, or if possible, explain how I can use the Sign URL within an iframe on the React side?
