如何使用youtube api将用户使用gmail帐户添加到我的直播流媒体视频?

Is it possible to add users to the live stream video from api request ??

If yes, how is it done. I have gone through many times in the api docs but could not find a thing on adding the selected users to the video from the api. Help me out guys.

P.S I already know that the users can be added from direct youtube dashboard and the users need to have gmail accounts. Here my question is how to add from the api request not from youtube livestream dashboard.

I dont think i need to upload my code here. However, my code is copy paste given from youtube developers guide. https://developers.google.com/youtube/v3/live/docs/liveBroadcasts

Also, my video is set to scope PRIVATE
