Make customUI actually custom

I would like when using the customUI to not have the SDK continue to pop up its own views. To be brief I will give just one example that has been frustrating me recently.

When my client user is spotlighted by the host and my client has audio muted. Zoom iOS SDK pups up a alert view asking the user to unmute. This brakes the customUI experience. Why not be consistent and expose that in the SDK and let the developer implement the UI?
