Extending SciFi UI PressEventKey to support Unity's New Input System

public class NeutrinoPressKeyEvent : PressKeyEvent
{
    [Header("Input System")]
    [SerializeField] NeutrinoInputSystemType inputSystem = NeutrinoInputSystemType.Hotkey;
    [SerializeField] InputActionAsset inputActionAsset;
    [SerializeField] string inputActionMapName;
    [SerializeField] string inputActionName;
    [SerializeField] bool ignoreWhenCanvasGroupNotVisible = true;
    [SerializeField] float canvasGroupAlphaThreshold = 1f;

    InputActionMap inputActionMap;
    InputAction inputAction;
    CanvasGroup canvasGroup;

    void Awake() {
        if (inputActionAsset != null && inputActionMapName != "" && inputActionName != "") {
            inputActionMap = inputActionAsset.FindActionMap(inputActionMapName, throwIfNotFound: true);
            inputAction = inputActionMap.FindAction(inputActionName, throwIfNotFound: true);
            inputAction.performed += _ => InputActionPerformed();

            // MARIO: for some reason, when home is visible from start, it calls OnEnabled() and OnDisabled() even
            // though it's actually active. That's why I keep it enabled and check gameObject.activeInHierarchy
            // instead of using the  methods to enable or disable inputActionAsset
            inputActionAsset?.Enable();
        }
        canvasGroup = GetComponentInParent<CanvasGroup>();
    }

    void Update()
    {
        if (pressAnyKey == true) {
            if (Input.anyKeyDown)
                ExecuteAction();
        } else if (inputSystem == NeutrinoInputSystemType.Hotkey) {
            UpdateForHotkey();
        }
    }

    void InputActionPerformed() {
        if (inputSystem != NeutrinoInputSystemType.InputAction) {
            return;
        }

        ExecuteAction();
    }

    void UpdateForHotkey() {
        // MARIO: changed from GetKeyDown to GetKeyUp to fix bug that multiple panels are called
        if (Input.GetKeyUp(hotkey)) { 
            ExecuteAction();
        }
    }

    void ExecuteAction() {
        // MARIO: all panels remain active, but hidden just with canvasGroup.alpha = 0, that's why
        bool ignoreBecauseNotVisible = ignoreWhenCanvasGroupNotVisible && canvasGroup != null && canvasGroup.alpha < canvasGroupAlphaThreshold;

        if (ignoreBecauseNotVisible || !gameObject.activeInHierarchy) {
            return;
        }
        pressAction.Invoke();
    }
}

public enum NeutrinoInputSystemType {
    Hotkey,
    InputAction
}

This is how it looks like in Unity's inspector tab.

The Hotkey is ignored when Input System is "InputAction" and vice-versa.
