I am trying to obtain all members of a SharePoint Site security group via Microsoft Graph API. I've been able to access our site's User Information List and locate the specific SP security group in the User Information List. However, I cannot expand the item to see who is in the SharePoint Site security group. How can I obtain SP site group members using Graph API? Is it possible to expand that item from the User Information List? Any insight is welcome! Thank you.
proc http url="https://graph.microsoft.com/v1.0/sites/root/lists/{User Information List ID}/items/{item ID, 5831 in this example}?expand=fields"
oauth_bearer="&access_token"
out=items;
run;
