How do i make UI seperated from main screen?

Godot Version

v4.5.1.stable.official [f62fdbde1]

Question

How do I make UI seperate from main screen, so it wont block main screen and it would be above it even when camera moves?
How can I add some borders that can always be seen on main screen, even if camera moves?

How can i make something like this? I tired using CanvasLayer, but it is only always inside of main screen, blocking some space on the upper part. Is there any way to make something like this?

[mrcook]

using CanvasLayer is the way

In this screenshot of the scene I setup the canvas layer around the blue line

here I add it to the scene I need

This is the result

the tutorial screen on the left pops out through code and a AnimationPlayer
