Disable 16x9 by defauld

I tried to use method ZoomVideoSetting.Setting_EnableAlwaysUse16v9({ bEnable: false }) to disable 16x9 proportions but it is still there. When I call method ZoomVideoSeeting.Setting_IsAlwaysUse16v9() it also returns true.

Could you provide more information how to use this methods? What is exact order? Should I run it before meeting started or after, etc.?

Thank you in advance

Which version?
