We are trying the example coming with ZOOM flutter Video SDK 1.7.0  
Local video does not start on iOS simulator (iPhone 14 iOS16.4).  
zoom.videoHelper.startVideo() returned ZoomVideoSDKError\_Session\_Video\_Device\_Error.

Does anybody see this? What is the cause and how to fix?

Thanks.

@hellinton.eduardo It turned out that iOS simulator does not provide camera functionality. We need to run tests on a physical iPhone instead.
