Get reference handle to the FleshAsset in the viewport

Hello,

I have created flesh Asset as per the training tutorial and placed it in the viewport . I have a c++ project where I want to capture a mouse drag event on the Flesh Asset . I have tried the following code

FHitResult HitResult;
GetHitResultUnderCursor(ECC_Visibility, true, HitResult);

But HitResult does not contain the desired FleshAsset .
How to get the handle to the Flesh Asset ?
