Detect object field in Inspector window was changed

How do I write a logic in script to detect if the object field has been changed in inspector window? I am using a script that executes in editor as well as play mode and I am altering OffsetPosition in the inspector window. The offset position is then copied to my GameObject. I want a function to detect if the gameObject has been changed in inspector window.

    public GameObject Offset;
    public Vector3 OffsetPosition; 
    public bool GameObject_NotChanged;

    void Update () {
         if(GameObject_NotChanged == true)
         {
           Offset.transform.position = OffsetPosition;
         }
    }

    void GameObject_Changed()
    {
       GameObject_NotChanged = false;
    }

You could use OnValidate

This function is called when the script is loaded or a value is changed in the Inspector (Called in the editor only).

like so

public GameObject Offset;
public Vector3 OffsetPosition; 

private GameObject _lastOffset;
private Vector3 _lastOffsetPosition;

private void OnValidate()
{
    if((Offset != _lastOffset || _lastOffsetPosition != OffsetPosition))
    {
        if(Offset)
        {
            Offset.transform.position = OffsetPosition;
        }
        

        _lastOffsetPosition = OffsetPosition;
        _lastObject = Offset;
    }
}
