How to get the 3D location of a click in unreal engine 4?

Question

I'm trying to do a board game in unreal engine 4. I've set up pawns and a board actors. However, I would like to be able to decide on which case of the board the player clicked. The board is one piece and I'm not sure splitting it up would render it nice.

Is there a way to get back the 3D position of a click in unreal engine ?

Thanks for any help !
