The build function should be called after creating an instance of the HMSSDK.
Await the result & if true then create HMSConfig object to join or preview a room.
Implementation
Future<void> build() async {
await HmsSdkManager().createHMSSdk(hmsTrackSetting, iOSScreenshareConfig,
appGroup, preferredExtension, hmsLogSettings, isPrebuilt);
}
