How to insert two HTML5 banners made in Adobe Flash into one HTML page?

Question

JavaScript

Actually, I remember we used to have SWF - and we inserted it using object - everything was simple and clear)
Now the customer sent 2 banners in HTML5 format: html page, images folder and .js file. As I understand it, the HTML file contains the code generated by the Adobe Flash program when exporting / publishing the video to HTML format.
Of course, I can dig deeper into the JS code, but something is all so cumbersome, some additional files - can I insert it into the FLA page somehow differently?
Or overtake FLA in AnimatedGIF?

Answer 1

Use an iframe.

Answer 2

I haven’t come across anything like this, but if this is a separate html page, then the first thing that comes to mind is frames
