supabase.Auth.CurrentSession returns null , c# client

Question

I'm using dotnet add package supabase-csharp as a c# client. I'm signed in var session = await supabase.Auth.SignIn(email, password); successfully, but when i tried to get the current user or session it get back as null:

var currentSession = _supabase.Auth.CurrentSession;
var currentUser = _supabase.Auth.CurrentUser;

The configuration:

builder.Services.AddScoped<Supabase.Client>(_ =>

new Supabase.Client(
    builder.Configuration["SUPABASE_URL"],
    builder.Configuration["SUPABASE_KEY"],
    new SupabaseOptions
    {
        AutoRefreshToken = true,
        AutoConnectRealtime = true,
    }));

Any hints related to this?
