Can't get acces to Action Map with New Input System via code

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

public class CharacterMovement : MonoBehaviour
{
    Animator animator;

    int isWalkingHash;
    int isRunningHash;

    PlayerInput input;

    private void Awake()
    {
        input = new PlayerInput();

        input.CharacterControls.Movement.performed += ctx => Debug.Log(ctx.ReadValueAsObject());
    }

Hi! Me and My friend are learning Unity.
The code above is taken from here

This code Works well at my Project. But when my friend types “input.CharacterControls” Visual studio marks it as Error and intellisense doesn’t suggest any Action maps.

Any tips how to fix it? (The name of action Map is correct and we’ve generated C# class at Input Actions)
