Can zoommtg.js library be used for webinars or just for meeting?

Does the zoom meeting sdk for javascript support webinar functionality or is it only for joining meetings?

And if so, how much customization is allowed? Can we integrate Webinar Q&A as well as Webinar survey questions? 

Hi Mingche, 

currently webclient only can join meetings. The requests you brought up currently are not on our roadmap, we will consider to add these based on amount of requests.
