Requesting permission for MediaProjection

[AdiXRHealth]

Hi, 
I have an android's native app. I tried to request media projection permission in the regular way and it showed the permission popup in an unreadable, unpressable 2d broken display. So I tried to use the Permission manager from the Wave VR sdk, but it doesn't allow requesting the permission with an intent. In the sdk package I seen an 

IMediaProjectionPermission

object, but any attempt to use it failed.

How can I request the permission???

currently (and urgently) on Vive Flow, in the future on Vive Focus as well.  

Thanks!
