Error Running jextract on d3d12.h

I have a question. Sorry for using Java based terminology:

Say I have obtained an object which is a MemorySegment, in this case
DXGIFactory1:

try (var scope = NativeScope.unboundedScope()) {
var dxgiFactory = scope.allocate(C_POINTER);
int hresult = dxgi_h.CreateDXGIFactory1(GUID(IID.IID_IDXGIFactory1),
dxgiFactory);
// Now I want to call equivalent of
dxgiFactory->EnumAdapters1(adapterIndex, &dxgiAdapter)
}

How does one call the EnumAdapters1 method on the dxgiFactory
MemorySegment? I searched through the generated Java source files
from running jextract on dxgi.h and the only MethodHandles I see are to the
"global methods" CreateDXGIFactory and CreateDXGIFactory1.
Basically my question is how does one call a member's method (non-global
method)?

Thanks very much.
