X-Frame-Options - HTTP | MDN[^]

If you can still load your page in an <iframe>, then either you haven't set the header properly, or you are using a really old browser which doesn't support the header - eg: Internet Explorer 7.

NB: In more recent browsers, the X-Frame-Options header is essentially obsolete. It can be replaced with the frame-ancestors directive of your content security policy.
