How to control official zoom client from my application

How to control official zoom client from my application.

Hi,

I’m developping Windows application.
I’m trying control official zoom client from this application.

I want to
・Add/Change background image.
・Send chat
・Start/Stop Attendee video

I found those functions from Zoom Windows SDK.
・VirtualBGSettingContext::AddBGImage
・VirtualBGSettingContext::UseBGImage
・IMeetingChatController::SendChat
・IMeetingVideoController::StopAttendeeVideo
・IMeetingVideoController::AskAttendeeToStartVideo
But I couldn’t control official zoom client from SDK.

Is Zoom Windows SDK able to control official zoom client?
Or is there any other way?

Thank you.
