How to Use Microphone at Hololens2?

Hello.

I Want use microphone at Hololens2

In the past, the user’s voice was captured and recorded through FVoiceModule based on the Windows desktop.
I changed to HoloLens and tried to use FVoiceModule, but it didn’t seem to work.
Other than that, normal C++ dlls are also not imported. (GetDllHandle)
Both relative and absolute paths are not allowed.
I have confirmed that the dll is in the appxbundle file.

Is there any other way?
