Manually decrypt cookies set by asp.net core identity

Based on what I learned from How to manually decrypt and asp.net core auth cookie I tried to do the similar. The only difference is that the cookie is set by asp.net core identity. Here is the piece in SetUp.cs:

    services.AddIdentity<ApplicationUser, IdentityRole>( options =>
        {
            options.Cookies.ApplicationCookie.AuthenticationScheme = "Cookies";
            options.Cookies.ApplicationCookie.DataProtectionProvider = DataProtectionProvider.Create(new DirectoryInfo(@"c:\shared-auth-ticket-keys\"));
        })
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders();

And here is how I tried to setup decrypt in homeController.cs:

    var cookies = HttpContext.Request.Cookies;

    var provider = DataProtectionProvider.Create(new DirectoryInfo(@"c:\shared-auth-ticket-keys\"));

    //Get a data protector to use with either approach
    var dataProtector = provider.CreateProtector("Identity.Application", "Cookies", "v2");

    //Get the decrypted cookie as plain text
    UTF8Encoding specialUtf8Encoding = new UTF8Encoding(encoderShouldEmitUTF8Identifier: false, throwOnInvalidBytes: true);

    foreach (var cookie in cookies)
    {
        byte[] protectedBytes = Base64UrlTextEncoder.Decode(cookie.Value);
        byte[] plainBytes = dataProtector.Unprotect(protectedBytes);
        string plainText = specialUtf8Encoding.GetString(plainBytes);
    }

But I always get the following error: The key {******-****} was not found in the key ring.

How to match up the key/dataProtectionProvider?
