Question How to render 2d sprite on 3d object perpendicular to camera?

Hello, I'm making a 3d game with an isometric-style camera that is locked on the player at 45 degrees (I'm not allowing rotations around the player). I want a cheap way to add grass to my ground plane, and found a transparent image of a tuft of grass. My goal is to randomly position that grass sprite on the plane, but have it appear perpendicular to camera. I believe this can be done as a material with shader graph, but I'm very new to Unity and was wondering how I would go about that?

Thanks!
