{
ValidateIssuer = false,
NameClaimType = ClaimTypes.Name,
RoleClaimType = ClaimTypes.Role,
};
options.Scope.Add("openid profile User.ReadWrite User.ReadBasic.All Sites.ReadWrite.All Contacts.ReadWrite People.Read Notes.ReadWrite.All Tasks.ReadWrite Mail.ReadWrite Files.ReadWrite.All Calendars.ReadWrite");

The simplest answer for you is to follow the "Get Started of ASPNET", and then change the logic to suit your requirement.
Do it your by yourself:
Use the Nuget to install the "Microsoft.Graph" and then modify the GraphScopes in configuration file of project(appsettings.json for NETCore).
"AzureAd": {
"Instance": "https://login.microsoftonline.com/",
"CallbackPath": "/signin-oidc",
"BaseUrl": "https://localhost:44334",
"ClientId": "your client id",
"ClientSecret": "your secret", // This sample uses a password (secret) to authenticate. Production apps should use a certificate.
"Scopes": "openid email profile offline_access",
"GraphResourceId": "https://graph.microsoft.com/",
"GraphScopes": "User.Read User.ReadBasic.All Mail.Send
}
Modify the configure service code as below:
services.AddAuthentication(sharedOptions =>
{
sharedOptions.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
sharedOptions.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
sharedOptions.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
})
.AddAzureAd(options => Configuration.Bind("AzureAd", options))
.AddCookie();
