Adding extra stuff through the published HTML of Storyline

Hello everyone,

As far as I know, Storyline is unable to embed stuff using embed codes, and I am trying to put certain stuff like a Padlet as an actual object rather than just a web object, as it shows the image below which is not the most aesthetically pleasing.

 

So, I was thinking I should just edit the published HTML of the package and plop the embed code into that, but it produced something like this:

I realised I didn't actually know where and how to plop it into the HTML properly. So, if anyone could provide some guidance that would be very helpful.

 

P.S. I realise I can just use Rise 360 to host these different assets and I have a version of that prepared if this plan doesn't work.

Thank you :D
