Issue description

How can I use the Node3DGizmo class? Where is the source code of this class? I could not use this feature for some reason.

Steps to reproduce

my code:
var gizmo = new Node3DGizmo();
error:
'Node3DGizmo' does not contain a constructor that takes 0 arguments

Minimal reproduction project

using Godot;
using System;

public partial class Gizmo : Node3D
{
	// Called when the node enters the scene tree for the first time.
	public override void _Ready()
	{
		var gizmo = new Node3DGizmo();
		//AddGizmo(gizmo);
	}

	// Called every frame. 'delta' is the elapsed time since the previous frame.
	public override void _Process(double delta)
	{
	}
}

Still, some docs were missing for this class so I'm adding them in #82681. What you should look at is EditorNode3DGizmo, which has ample documentation.

Actually, what I was trying to explain was that the Node3DGizmo class could not be created, I thought it was a bug. I think it is necessary to use the EditorNode3DGizmo class, but I don't understand why this Node3DGizmo was created, if it cannot be used?

@unicornlox It's an abstract class, we have a few in our API. You are not supposed to use them directly.

In this case, the reason it exists is purely internal, so updating the docs to mention that users shouldn't bother with the class should be sufficient.
