Infinitive category and subcategory

I am creating a system of categories and subcategories Infinity. For now I have managed to create two-level categories and subcategories eg.

CATEGORY_1 --SUBCATEGORY_1 CATEGORY_2 --SUBCATEGORY_2

I would like to create infinite levels. how can I do?

categories tables

    public function up()
    {
        Schema::create('categories', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->bigInteger('parent_id')->default(0);
            $table->string('name');
            $table->boolean('status')->default(1);
            $table->timestamps();
        });
    }

Models\Category

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    use HasFactory;

    protected $fillable = [
      'name',
      'parent_id'
    ];
    
    public function children()
    {
        return $this->hasMany('App\Models\Category', 'parent_id');
    }

}

CategoryController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
use App\Models\Category;

class CategoryController extends Controller
{
    public function index(){
      $categories = Category::with('children')->where('parent_id', '=', 0)->get();

        return view('backend.category.index')->with([
          'categories'  => $categories
        ]);

    }

    public function create(){
      $categories = Category::with('children')->where('parent_id', '=', 0)->get();

        return view('backend.category.create')->with([
          'categories'  => $categories
        ]);
    }

    public function store(Request $request)
    {
      $validatedData = $this->validate($request, [
            'name'      => 'required|min:3|max:255|string',
            'parent_id' => 'sometimes|nullable|numeric',
            'status' => 'required'
      ]);
      Category::create($validatedData);

      return redirect()->route('category.index')->withSuccess('You have successfully created a Category!');
    }
