Override Webcam, Microphone Authorization Style

Hello Everyone,

I'm currently making use of the microphone capabilities for the Web version of the software I'm developing. Currently, when you run while using the Microphone class, a Unity created window appears called the Unity Web Player Authorization Request. I'm curious if there is a way to modify this window to style with my custom GUI. I'd much rather put this on an options menu and attach the functionality to a toggle. Does anyone know if this is possible? I've tried to find references to this window without any luck.
