Checkbox not working as intended in Mixed reality toolkit V2

Question

Checkboxes are currently unusable in the new toolkit, as you cannot bind functions to states.

There is a development commit on GitHub, but it's not usable yet, so I need a script to work around, without changing the toolkit.

Should be able to easily set starting state, and call functions on state change - which you currently can't.

Found a solution that works without changing the toolkit, and should work on newer versions.

using UnityEngine;
using Microsoft.MixedReality.Toolkit.UI;
using UnityEngine.Events;

[RequireComponent(typeof(Interactable))]
public class CheckBoxInteractableSwitch : MonoBehaviour
{

    public bool startChecked = true;

    public UnityEvent OnCheck;
    public UnityEvent OnUncheck;

    private Interactable interactable;
    private int state = 1;

    void Start()
    {
        interactable = GetComponent<Interactable>();

        if (OnCheck == null)
            OnCheck = new UnityEvent();
        if (OnUncheck == null)
            OnUncheck = new UnityEvent();

        OnCheck.AddListener(Checked);
        OnUncheck.AddListener(UnChecked);

        //works with 2 dimensions only
        if (startChecked)
        {
            if (interactable.GetDimensionIndex() == 0) interactable.IncreaseDimension();
        }
        else
        {
            if (interactable.GetDimensionIndex() == 1) interactable.IncreaseDimension();
        }

    }

    void Update()
    {
        if (interactable == null) return;

        //state check
        if (state != interactable.GetDimensionIndex())
        {
            state = interactable.GetDimensionIndex();
            if (state == 0) OnUncheck.Invoke();
            if(state == 1) OnCheck.Invoke();
        }
    }

    private void Checked()
    {

    }

    private void UnChecked()
    {

    }
}

Works with checkboxes only (2 dimension), you can set the default state for the checkbox, and you can subscribe to states on state changes.
