How to use Hololens2's dictation mode in UE4?

In the development of UE4+Hololens2, I wish to convert the words I said when using hololens2 into text in real time(Speech to Text). At present, I have not found the relevant calling method in UE4, and there is no official document. I found that the dictation mode based on hololens is supported by Unity, Does UE4 support it and how to use it?

Take a look at this plugin GitHub - microsoft/Microsoft-OpenXR-Unreal: The Microsoft OpenXR plugin is an Unreal Engine game plugin which provides additional features available on Microsoft's Mixed Reality devices like the HoloLens 2 when using OpenXR.
