iPhone(safari) video player in Rise 360

Hi,

We've created an eLearning that has a few iframe videos in it.

When playing the videos on the published eLearning on a PC and on Android, everything works great.

On iPhone(Safari)  however, the content does not load at all.

Here's the iframe (link is partially redacted since the content is internal):

<iframe src="https://drive.google.com/file/d/REDACTED/preview" width="1920" height="1080" allow="autoplay"></iframe>

Thanks in advance!
