Splitting the screen into 2 sides with a line

Hello. I want to make a scene in Unity where you have circles (sprites) on screen and what should happen is that there a line needs to be spawned and it will tell you how many circles are on one side and how many on the other.
How can I do this? should the line be made with linerenderer or with a png sprite or what?
And also how do I differ the sides?
I really need this, it’s very important for me.
Thank you very very much for helping! :slight_smile:

please help
