Post communication is a feature of the pro version.
The text you referring to is:
If you mix http and https pages you NEED to enable “Use post message for communication” and follow example 53 for this advanced setup (pro version needed)
Do you maybe have a older version of the plugin where this text is different?

I’m not using the pro version, never have. My version is 7.3.1. I have no older version that ‘maybe'(?) shows a different text. Why would I? I don’t know why you marked this as resolved merely by your somewhat confusing statements but I’ll resolve it by deleting Advanced iFrame and use something else.
Thanks.
I marked it as resolved because I have answered your question!
Post communication is a feature of the pro version! You have the free version where this is not available. So you need to upgrade to pro or look for a different plugin/solution which you can of course do.
You can enable the pro administration also in the free version to see all options where post communication is a part of.
Feel free to find another plugin that will solve e.g auto height with https in http pages. As far as I know you then have to implement this by yourself.
Best, Michael
