How to be compatible with lower versions of browsers？

@bcantoni @jimjag @illonage @d45 @alicemhsiao 
I used embedding-api-v3 to embed tableau reports on my smart TV, but the system webview version is too low (webview 44.0) and incompatible with `type=module`, which causes the tableau reports to be displayed normally, due to region and device limitations, I can't update webview either, Is there any good solution?
