I can't see who is in the waiting room for Webinars Plus

My team recently held a webinar using Webinars Plus and we noticed that we couldn’t visibly see who was in the waiting room. We could only see that 20 people were in the waiting room and everyone was let in once the Webinar started. We want to have greater control over who can enter our webinars. I know in Zoom Meetings you can see who is in the waiting room. Is there a function available for Webinars Plus that allows us to manually approve people into our webinar, or allows us to see who is in the waiting room?
