Don't show the audience the "Presenting..." banner because it's misleading.
When a meeting is being recorded, and when a presenter is presenting content, they will see a banner on their own screen that displays "Presenting...". This should only be viewed by the presenter. The audience shouldn't see this because it's misleading. I have audience members interrupting saying they are getting a presenting notification when it reality they are not actually presenting. They are just seeing the banner on the presenters screen.
