AskAllToUnmute is missing in C# wrapper

Hey @jonskeet,

Thanks for using the dev forum!

I will forward this to the team to implement. However, the C# wrapper is not actively managed by Zoom, so a timeline is unknown. However, if you need this interface sooner, you can manually add it to the wrapper. Here is an example of how to do this: Customized UI C# callback.

Thanks!
Michael
