How to consume ISwapChainPanelNative interface from SwapChainPanel IntPtr

From C# code I'm creating Microsoft.UI.Xaml.Controls.SwapChainPanel instance and getting its IntPtr like this:

    WinRT.IObjectReference nativeObject = ((IWinRTObject)MySwapChainPanel).NativeObject;
    IntPtr panelIntPtr = nativeObject.ThisPtr;

    var cli = new MyCliClass();
    cli.SetRenderer(panelIntPtr);

And in C++/CLI project I'm trying to use it like this:

#include <d3d11_2.h>
#include <d2d1_2.h>
#include <windows.ui.xaml.media.dxinterop.h>

void TestPlayerCli::MyCliClass::SetRenderer(System::IntPtr swapChainPtr)
{
    ISwapChainPanelNative* panelNative;
    reinterpret_cast<IUnknown*>(swapChainPtr.ToPointer())->QueryInterface(IID_PPV_ARGS(&panelNative));
    //not working either
    //panelNative = (ISwapChainPanelNative*)swapChainPtr.ToPointer();

    IDXGISwapChain2* m_swapChain;
    //init m_swapChain code...
    HRESULT hr = panelNative->SetSwapChain(m_swapChain);
}

What would be the proper way to get ISwapChainPanelNative object from provided swapChainPtr in this case?

For WinUI3 you need to #include <microsoft.ui.xaml.media.dxinterop.h> rather than <windows.ui.xaml.media.dxinterop.h>.
