Use Microsoft Graph to query user groups in ASP Net Core 2.1

It is possible to use Microsoft Graph in an old ASP Net Core 2.1 application?

My application is using OpenID Connect to authenticate users but I need to query Microsoft Graph to get the users groups. ( Previously this was done using Azure AD Graph )

Can someone point me to some old examples of code that are working with 2.1 framework. Most of the examples I found are with new framework versions.

// Microsoft.AspNetCore.Authentication.OpenIdConnect, Version=2.1.2.0

          .AddOpenIdConnect(option =>
          {
              option.ClientId = ClientId;
              option.ClientSecret = ClientSecret;
              option.Authority = $"https://login.microsoftonline.com/{Tenant}";
              option.Resource = "https://graph.microsoft.net";
              option.SignedOutRedirectUri = SignedOutRedirectUri;
              option.CorrelationCookie.Name = "cookie name";
              option.NonceCookie.Name = "nonce name";
              option.NonceCookie.SecurePolicy = CookieSecurePolicy.Always;                
              option.CorrelationCookie.SecurePolicy = CookieSecurePolicy.Always;
              ....
          }
