title: Get SharePoint Groups (not AD groups) using Graph API
body: <p>Is there a method to retrieve SharePoint Groups using Microsoft Graph?</p>
  
  <p>I can get Azure Directory groups using <code>https://graph.microsoft.com/v1.0/groups</code> but what I'm looking for are SharePoint Groups.</p>
  
  <p>I could get a <code>SiteCollection</code> using <code>https://graph.microsoft.com/beta/sites/{id}</code> but I couldn't seem to get the SharePoint Groups in site collection.</p>
