Get access token using only email/refresh_token with C#

I have a table in a database with emails and their refresh tokens of multiple Hotmail/Outlook.com accounts (nothing else).

I'm trying to create an Access Token using the Refresh Token but I can't find any code using Microsoft.Identity.Client or Microsoft.Graph libraries to perform that action.

Here is the partial code in a console application:

static void Main(string[] args)
{
    /* other code */
    string email, refreshToken; // obtained from database
    TokenCache tokenCache = new TokenCache(); // how do i "fill" this object?

    ConfidentialClientApplication cca = new ConfidentialClientApplication(
        "appId",
        "redirectUri",
        new ClientCredential("appSecret"),
        tokenCache,
        null);

    IAccount account = cca
        .GetAccountsAsync()
        .Result
        .FirstOrDefault();

    AuthenticationResult result = cca
        .AcquireTokenSilentAsync(new string[] { "scopes" }, account)
        .Result;

    GraphServiceClient client = new GraphServiceClient("https://outlook.office.com/api/v2.0/",
        new DelegateAuthenticationProvider((requestMessage) =>
        {
            requestMessage.Headers.Authorization =
                new AuthenticationHeaderValue("Bearer", result.AccessToken);
            return Task.FromResult(0);
        }));

    var msgs = client
        .Me
        .MailFolders
        .Inbox
        .Messages
        .Request()
        .Select(m => new { m.Subject, m.ReceivedDateTime, m.From })
        .Top(10)
        .GetAsync();

    /* more stuff to do */
}

I have been able to do this using PHP but now I need it to do it in .net

UPDATE: I will show the complete code using the answer of Marc LaFleur

ConfidentialClientApplication cca = new ConfidentialClientApplication(
    appId,
    redirectUri,
    new ClientCredential(appSecret),
    new TokenCache(),
    null);
AuthenticationResult result = (cca as IByRefreshToken).
    AcquireTokenByRefreshTokenAsync(scopes, refreshToken).Result;

GraphServiceClient client = new GraphServiceClient(
    "https://outlook.office.com/api/v2.0/",
    new DelegateAuthenticationProvider((requestMessage) => {
            requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
            return Task.FromResult(0);
    }
));

var msgs = client.Me.MailFolders.Inbox.Messages.Request().
    OrderBy("receivedDateTime DESC").
    Select(m => new { m.Subject, m.ReceivedDateTime, m.From }).
    Top(10).
    GetAsync().Result;
