Zoom Screen Sharing Issue on IOS devices

Hi there! I'm developing AI Wardrobe app using flutter framework in which zoom audio/video calling and screen sharing features are required. I've integrated zoom SDK and followed all it's required steps in order to achieve this functionality but the main issue I'm facing is that I'm unable to see screen share extension in the meeting control panel or toolbar of IOS devices, even after following all it's required steps. (On android device, screen sharing feature is working fine). Please guide me related to this issue.

Followed this zoom's official documentation: https://developers.zoom.us/docs/video-sdk/ios/share/
