UNSOLVED Google Slides iFrame Doesn't Show

[loretod]

Greetings-

I am trying to embed a Google Slide presentation using many of the available iFrame modules and for some reason it doesn’t display. I am able to display the edit/ document of the slide but not the published url. I’ve also been able to embed random web pages just not a published Google Slide. I’ve tried:

• Setting the document permissions to anyone can view and edit.
• Change the font color- maybe black text doesn’t show?
• Multiple variation of the published URL with no success
• Creating a slide on a non google suite account

Here is a sample URL I would like to embed:
https://docs.google.com/presentation/d/e/2PACX-1vQMRAbat3lvAQczi4tPJ3yBhsXrvU9YxuDjPnFRrYTTUTBth2s9L9G-Nj6N4LNaGfXqa_GKwlVJNasZ/pub?start=true&loop=true&delayms=3000

I’m thinking it is something with the permissions? URL?

Any help is most appreciated!
