How to take a screenshot on UWP?

Hi

Anyone now how to take a screenshot in Monogame on UWP?

I had a look at RenderTargetBitmap but it does not capture if, quote “Custom DirectX content (your own swap chain) inside a SwapChainBackgroundPanel or SwapChainPanel can’t be captured using RenderTargetBitmap.”. I’m using SwapChainPanel for Monogame.

Thanks
