MS Graph API for SharePoint

Question

I would like to know if we are doing it the right way but seeing access denied and empty result when using below API calls.

1. When I execute https://graph.microsoft.com/v1.0/sites API
   I am getting empty result:
   {
   "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#sites",
   "value": []
   }
2. When I execute https://graph.microsoft.com/v1.0/sites/root
   I am getting result:
   {
   "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#sites/$entity",
   "createdDateTime": "2013-12-23T14:54:12.67Z",
   "description": "",
   "id": "xxxx.sharepoint.com,292b9b4c-5126-460a-915b-fa3511631211,d7852db4-e891-4e0b-aa80-db96f0551caq",
   "lastModifiedDateTime": "2020-10-28T14:13:24Z",
   "name": "",
   "webUrl": "https://xxxx.sharepoint.com",
   "displayName": "Employee Home",
   "root": {},
   "siteCollection": {
   "hostname": "xxxx.sharepoint.com"
   }
   }
3. When I execute: https://graph.microsoft.com/v1.0/sites/root/sites to get all sites under root
   I am getting Access denied:
   {
   "error": {
   "code": "accessDenied",
   "message": "Access denied",
   "innerError": {
   "date": "2020-10-28T17:37:04",
   "request-id": "22030e19-bce3-4308-86aa-xxxxxxxxxxx",
   "client-request-id": "22030e19-bce3-4308-86aa-xxxxxxxxxxx"
   }
   }
   }
   End goal is to be able to work with SharePoint List and list items.
