How to detect x-frame-options when loading a website in iframe

Loading external website in an iframe is getting blocked because of x-frame-options in response headers. I want to detect what is the value for x-frame-options and based on that value i want to show an alert to the user. How can we detect/extract x-frame-options from the response headers for the given url even if it has redirects?

I'm not sure under what conditions you want to check this like you have a website that allows to embed such content or you want to do this locally.

There is an extension for Firefox that allows this.

I want to do it programmatically as i don't want end user to go to settings and disable enhanced tracking protection or installing some extensions in order to work with embeded content. So if i'm able to detect the x-frame-options i can ask user to launch the same url in new window by providing a button(Latest Firefox is doing similarly but i want to handle it in our website so that solution will work across the browsers).

Attached firefox implementation screenshot for reference.
