Hi, I am looking for some feedback on this before I dive too deep. I have a login screen scene and a game loop scene. I needed Nakama connection on both scenes, initially had some issues with having 2 sessions open at the same time due to opening one connection on the login screen and another one on the game loop scene when moving from login to game. The only option I could find to fix this is to create an instance of my ConnectionManager and just use the instance in the game scene. First time working with Nakama, unity, and c# so are there any problems with my current code or way to improve it before I go further?
public class ConnectionManager : MonoBehaviour
{
public static ConnectionManager instance;
// Connection Info
private string scheme = "http";
private string host = "*;
private int port = *;
private string serverKey = "*";
// User Info
// @_username is required only for registration purposes
private string _username;
private string _email;
private string _password;
private string _passwordConfirmation;
// PlayerPrefs
private const string SessionPrefName = "Session";
// Connections vars
private IClient _client;
private ISession _session;
private ISocket _socket;
public IApiAccount Account;
public IClient Client { get; set; }
public ISession Session { get; set; }
public ISocket Socket { get; set; }
// Matchmaking

SceneManager.LoadScene("GameLoop");

{
_username = username;

if (_email != null && _password != null)
{
try
{
// Create a new session
Session = await Client.AuthenticateEmailAsync(_email, _password, create: false);
// Store the session so we can restore it later if needed
PlayerPrefs.SetString(SessionPrefName, Session.AuthToken);
Socket = Client.NewSocket();
await Socket.ConnectAsync(Session, true);
if (Socket.IsConnected == true)
