Difficulty pulling iframe content

[loopcoder]

I appreciate the outstanding performance of the "rrweb" library, particularly its "record" feature. I am truly grateful for this. However, I find the "rrweb-snapshot" functionality challenging when it comes to dealing with complex scenarios involving nested iframes within a webpage. Do you happen to have a sample code that demonstrates a snapshot feature that works as efficiently as the "record" feature in rrweb?
