typedef void __fastcall (__closure *TDisplayRationaleEvent)(System::TObject* Sender, const _dt_System_Permissions_3 APermissions, const System::Sysutils::_di_TProc APostRationaleProc);
Callback type to provide an explanation to the user for the need for a permission.
A rationale string for previously denied permissions that were pre-loaded. When the rationale display is over, be sure to call the
APostRationalProc routine, which will then request the required permissions. This type is compatible with an event handler method.
