Like if you are live streaming you just have to reach out to your audience and communicate with them just explaining to them and showing+telling them different things
From my experience, some good ways to involve your audience in a theatrical performance, is to have them talk back. Ask them a question, and then they can all shout an obvious universal answer. For example, the performers may say "When I say Brainly, you say Yay! Brainly--" then they can respond. Or, you can say, non directly, but to make it seem like your speaking and interacting, you can say "hey, kids!" or, "parents, are we having fun, tonight?" or things like that. I hope that I helped :)
