Need Assistance: Code to embed different URLs on dynamic pages

Hi All
I want to be able to embed an iFrame that links to unique URL’s on different dynamic pages. I know the basic dynamic pages on WIX does not allow for this but there must be a way to code it?
I have no coding background so any input would be greatly appreciated!

Read in docs about iframe and postMessage and onMessage. You need to script your code within the html you add to the HTML Component and make that code take in the data through onMessage from Wix Code and then set the iframe in your code to the src you want to using the postMessage function in Wix Code.

Or if it would work just set the src of a html component to the dynamic url if that works.

Can you show an example how to code it please?
