Iframe Amazon, Semrush, Google, twitter

Hello, I would like to be able to make a hidden Iframe inside my website. the reference site of the Iframe is Amazon, Semrush, Google, twitter, but for example amazon doesn't let you make iframes. [login to view URL] You could program a code so that if it was seen inside my webs? The idea is that this code is hidden as much as possible in case an Amazon reviewer comes and can't find it.
