ARSessionOrigin deprecated, but then the suggested 'XROrigin' can not be found

I’m starting a new AR Foundation 6 project and making the 1st script, like I did in version 5 with other projects.
Its telling me ARSessionOrigin is deprecated and I should use XROrigin instead. However, changing to XROrigin results in a error: “not found or incorrect namespace”. Can Unity give a more descriptive error so we also know which namespace to use please

using UnityEngine;
using UnityEngine.XR.ARFoundation;
using UnityEngine.XR.ARSubsystems;

public class ARTapToPlace : MonoBehaviour
{
    private XROrigin arOrigin;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

    }
}

You need different namespaces (using Unity.X.X).
Visual studio should be able to automatically find them

I dont get the error in VS Code, only in Unity. As far as VS Code is concerned, the code is perfectly fine, but when I save and go back to Unity, Unity gives that error. How can I find which namespace to use?

I never used VSCode, as I’ve hear the Unity integration wasn’t great. Just open the XROrigin script to see

5 
using Unity.XR.CoreUtils;

The namespace is shown on the scripting API reference in case your IDE isn’t able to show you: Class XROrigin | XR Core Utilities | 2.3.0

This is a sign that your VSCode isn’t configured properly to work with Unity. Microsoft maintains a plugin that will give you features like auto-imports. Notably, you need to install the Visual Studio Editor package in the Unity Editor.

I restarted and now VS Code underlines it in yellow as a warning.
is there a particular keyboard shortcut I should press to do the auto-imports?
