Trying to place a an object in AR on a detected plane, using Visual Scripting (Bolt) in Unity

I am trying to convert the script below to a visual script (Bolt) in Unity.
The application uses AR foundation to detect a plane, then place a game object on the plane when you tap the screen.

Here is a video of that (The demonstrations starts at 1:30)

The script works, I am just not that familiar with Visual Scripting.

Here is the script

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR.ARFoundation;
using UnityEngine.XR.ARSubsystems;

[RequireComponent(typeof(ARRaycastManager))]

public class PlaceScript : MonoBehaviour


{
    public GameObject portalToPlace;
    private GameObject spawnedPOrtal;
    ARRaycastManager arRaycastManager;
    Vector2 touchPosition;
    static List<ARRaycastHit> hits = new List<ARRaycastHit>();
    


    // Start is called before the first frame update
    void Start()
    {
        arRaycastManager = GetComponent<ARRaycastManager>();
    }

    // Update is called once per frame
    void Update()
    {
        if (!TryGetTouchPosition(out Vector2 touchPosition))
            return;

        if (arRaycastManager.Raycast(touchPosition, hits, TrackableType.PlaneWithinPolygon))
        {
            var hitpose = hits[0].pose;
            if (spawnedPOrtal == null)
            {
                
                spawnedPOrtal = Instantiate(portalToPlace, hitpose.position, hitpose.rotation);
                //spawnedPOrtal = Instantiate(portalToPlace, hitpose.position, portalRotation.rotation);
            }
        }

       
    }

    

    bool TryGetTouchPosition(out Vector2 touchPosition)
    {
       if (Input.touchCount > 0)
        {
            touchPosition = Input.GetTouch(0).position;
            return true;
        }

        touchPosition = default;
        return false;

    }
}

and this is what I have in VS:

You can see in red where the errors are so far, although that may be only the tip of the iceberg.
