How to iframe My Square space site?

Site URL: https://redkiteseo.com/

Hello

Does anybody know how I can iframe my squarespace website please?

I wanted to iframe it on my Google site, but it keeps saying wont connect, i think because of a x frame blocker?

Which is bizzare, becuase I can iframe the www.squarespace.com but not my own website.

It's a new site so probably 7.1 version at a guess.

Any help is much appreciated, thanks.
