  + Note that when executing tenant level SharePoint Online commands, the CLI will attempt to autodiscover your tenant URL.
  +
  + It will first check for the presence of an environment variable containing the tenant URL, which can be set by using [`m365 spo set`](../../cmd/spo/spo-set/) command.
  +
  + If this cannot be found, a request will be made to the Microsoft Graph. For this request to be successful, you must ensure that you have at least the `Sites.Read.All` permission granted to your application.

  This completes the configuration required in the Azure portal. We can now move onto configuring the CLI for Microsoft 365 to use our custom application to login to Microsoft 365.
