I want to show a .ppt or .pptx in an iframe but I don't use file URLs in front-end, I only have access to a blob url or a data url. I kind of ruled out Blob on my own as in that it's not going to work but I was wondering if anyone ever got a Data URL to work?

And I was also wondering about how secure these embeds are to use for business related purposes? I know third party is never really a good idea...

Would love to hear from you guys, documentation if you guys can find it is also welcome (I couldn't).
