iFrame which is used to load documents through s3 bucket url not getting recorded

In my webpage i am trying to load documents in an iFrame using an s3 bucket url. In my recorded session i see iframe is loaded but loading of document inside that is not captured.

Went through openreplay document and understood that capturing is not supported for cross domain iframes.

Is there any workaround i can get for this?

Correct. We only support same-domain iFrames for now. Having said, we have plans to support cross-domains iFrames over the coming releases (by end of Q2 this year).
