Resizing speaker's camera view during screen sharing

Meeting SDK iOS
1

we wish to make the speaker’s camera window larger when viewing his shared screen, e.g. shared screen and speaker’s camera are occupying 50% of the screen each 

Any hints on how to do that ?

Hi, currently Zoom iOS SDK doesn’t support in meeting UI. Please keep your eyes closely on this forum as we will announce new updates for iOS SDK.
