iframe plugin: Embedded iframe not responsive. Do I need iframe Pro?

Hello,

I am currently working with a responsive WordPress theme and I’m having difficulties embedding an html page to particular page on my website. The html page is currently saved in my cPanel and I managed to get it to embed it and function almost perfectly on my website. However, I cannot get it to function responsively. On the other hand, when I load the URL of the html page directly to the browser it does function responsibly, so something is happening in the embedding process. What I’m placing on the editor is the following, with the correct source link of course:

[iframe src=”https://[link]” width=”100%” height=”1007″ allowtransparency=”true” frameborder=”0″ allowfullscreen=”true”]

I also tried this but got no results:
[iframe src=”[link]” enable_responsive_iframe=”true” allowtransparency=”true” frameborder=”0″ allowfullscreen=”true”]

Am I missing something? Also I did notice that a responsive iframe can be achieved by purchasing the pro version of the iframe WordPress plugin. However, I’m certain there’s another way. Please let me know if you are aware of another method. Ultimately, I will have to get the Pro.

I must mention that the html page I am trying to embed should work like the following: https://iconasys.com/Downloads/Apple-Watch-360-View/iframe.html

These are the instructions from IconAsis:

Their instructions mention nothing about responsive iframes and their support staff has not been able to help me on this matter.

Please let me know if you are aware of a solution, I would really appreciate it.

Thank you
