this is the first script

public class PlatformerCharacter2D : MonoBehaviour
    {
               public bool m_FacingRight = true;

this is the second

namespace GameAssets._2D
{

   
    public class ArmRotation : MonoBehaviour
    {
        public int rotationOffset;
        public float rotz;
        public float MinRot;
        public float MaxRot;

        private PlatformerCharacter2D m_Character;

        // Start is called before the first frame update
        void Start()
        {

            m_Character = GetComponent<PlatformerCharacter2D>();
        }

        // Update is called once per frame
        void Update()
        {
            rotation();
            if (rotz>=MinRot && rotz<=MaxRot)
            {
                transform.rotation = Quaternion.Euler(0f, 0f, rotz + rotationOffset);
            }

            if(m_Character.m_FacingRight)
            {
                Dbug.LorWarning("some");
<            }

            //need to lock the rotation and reverse the arm when he walk left
        }
