How do I save toggle state ?

     public bool isMuted=false;



     void Start()
     {

         isMuted = PlayerPrefs.GetInt("MUTED") == 1;
         AudioListener.pause = isMuted;
         PlayerPrefs.GetInt("MUTED");

     }


     public void MutePressed()
     {
      
             isMuted = !isMuted;
             AudioListener.pause = isMuted;
             PlayerPrefs.SetInt("MUTED", isMuted ? 1 : 0);
       
     }
