Put 3D object at edge of screen

If I have a 3D object (actor) and I want it to be attached to the edge of the screen, either top, bottom, right, or left, how do I do it in blueprint?

I don’t use HUD because I want the actor to interact with the world in terms of rendering & collision. So it can react to various light source and have cool material effects on the actor. And also it will interact with other actors in the world whenever they collide.

I’ve read other similar topics, like making it a static mesh component inside the character actor, which also has a camera component. But they don’t address my concern.

I just want it to appear at the edge of the screen regardless of the actual screen size in various devices. Can someone help?
