Can I display the calendar from outlook with outlook api? Xamarin form

Question

I am able to authenticate with MSAL and retrieve the calendar's events in a Listview

However this is not what I want, is it possible to list out the whole calendar from outlook?

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

    var calendar = await graphClient.Me.Calendar
        .Request()
        .GetAsync();

Tried using both of these but theres nothing displaying.

var queryOptions = new List<QueryOption>()
{
    new QueryOption("startDateTime", "2017-01-01T19:00:00-08:00"),
    new QueryOption("endDateTime", "2017-01-07T19:00:00-08:00")
};

var calendarView = await graphClient.Me.Calendar.CalendarView
    .Request( queryOptions )
    .GetAsync();

Can I assume I need to create my own layout/calendar to store the events?

I am fairing new to C# so please bare with me.

Microsoft Graph API ensures that the app can communicate with Outlook.com (Microsoft Account) or Office 365 (Enterprise Account). So you could invoked the following code in Code Behind .

var client = new GraphServiceClient("https://graph.microsoft.com/v1.0",
      new DelegateAuthenticationProvider(
      async (requestMessage) =>
      {
         var tokenRequest = await App.IdentityClientApp.AcquireTokenSilentAsync(App.Scopes, App.IdentityClientApp.Users.FirstOrDefault());
         requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", tokenRequest.AccessToken);
      })); 
   var events = await client.Me.Events.Request().GetAsync();
   var list = events.ToList();
   YourListView.ItemsSource = list.Take(5);
