Draw 2d paper sprite on top

Hello, Im kinda new to ue4 and im trying to make a Augmented Reality looking 3D UI. Im using textures on 2D sprites for my icons and buttons, but sometimes they end up behind objects since they are in the 3D world.
Is there any way to make the 2Dpapersprites be drawn on top of everything else?

I’ve seen people use Translucency Sort Priority but does that work with 2Dsprites? and if it does, how do I make it work?
