Lan Host Netwroking Room List?

So I am trying to make a server or room list using the lan host and client situation, not the matchmaking services. I don't know how to access the rooms if it is not created using the matchmaking feature. Is it possible to create a list of rooms without using matchmaking and if so what command would I use. I will add the small script that I have made below, and thanks for the help!

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine.UI;
 using UnityEngine.Networking;
 using UnityEngine.Networking.Match;
 using UnityEngine;
 
 public class joinGame : NetworkBehaviour {
 
     List<GameObject> roomList = new List<GameObject>();
     private NetworkManager networkManager;
     [SerializeField]
     private GameObject roomListItemPrefab;
     [SerializeField]
     private Transform roomListParent;
     // Use this for initialization
     void Start () {
         networkManager = GetComponent<NetworkManager>();
         ClearRoomList ();
         AddRommsList ();
     }
     
     // Update is called once per frame
     void Update () {
         
     }
         
     void AddRommsList () {
         for (int i = 0; i < networkManager.matchHost.Length; i++) {
             GameObject roomGO = Instantiate (roomListItemPrefab);
             roomGO.transform.SetParent (roomListParent);
         }
     }
 
     void ClearRoomList () {
         for (int i = 0; i < roomList.Count; i++) {
             Destroy (roomList [i]);
         }
         roomList.Clear ();
     }
 }
