I want to create a popup in UWP,

1. It can be clicked anywhere from a canvas
2. It should be with a triangle pointer
3. The main popup can be moved dynamically but pointer should always point in the clicked point

Similar to this image,

I have tried with Flyout and Stackpanel as the content of flyout. And in stack panel I have added a textbox and polygon as triangle. But I could not dynamically move the flyout. Also, it gives a transparent background behind the total control (flyout and stackpanel) which I could not remove. Any help will be appreciated.
