Unity : How can a script itself creates gameobject at Runtime and attach itself to it or [Creating game-object directly from script that is not attracted to any game objects ]?

ScriptSelfInstancimatedObject.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SelfInstanciated : MonoBehaviour
{

    [RuntimeInitializeOnLoadMethod]
    static void Init()
    {
        GameObject instance_of_game_object = new GameObject();
        instance_of_game_object.transform.position = Vector3.zero;
        instance_of_game_object.name = "Self_InstanciatedGameObject_byHisScript";
        instance_of_game_object.AddComponent<SelfInstanciated>();

        /*
         * Script itself creates gameobject at Runtime and attach itself to it.
        */
    }

    // Start is called before the first frame update
    void Start()
    {
        Debug.Log("Hello! I am born from script! ( No game Object needed!)");
    }

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