im working on a dungeon crawler but i can't figure out how to make rooms connect i can't find anything helpful on google

current code:

public class Dungeon : MonoBehaviour 
{
    public Tile GroundTile;
    public Tile WallTile;
    public Tilemap tilemap;

    List<Room> rooms = new List<Room>();
    void Start () 
    {
        for(int i = 0; i < 10; i  )
        {
            rooms.Add(new Room(10, 10, new Vector2Int(i * 20, 0)));
        }
        for(int i = 0; i < 10;i  )
        {
            if(i > 0 && i < 10)
            {
                rooms[i].position = rooms[i - 1].Connect(rooms[i]);
            }
        }

        AddRoomsToTilemap();
    }
    public void AddRoomsToTilemap()
    {
        foreach(Room room in rooms)
        {
            for (int x = 0; x < room.width; x  )
            {
                for (int y = 0; y < room.height; y  )
                {
                    if (room.tiles[x, y] == 0)
                    {
                        tilemap.SetTile(new Vector3Int(x   room.position.x, y   room.position.y, Random.Range(0, 10)), GroundTile);
                    }
                    else
                    {
                        tilemap.SetTile(new Vector3Int(x   room.position.x, y   room.position.y, 0), WallTile);
                    }
