There are mistakes in the sample instructions that need correction

Specifically, I'm having trouble following this step: Configure Permissions - under the "Permissions to other applications" section, select application "Azure Active Directory" (this is the Graph API), and under the second permission (Delegated permissions), select "Access your organization's directory" and "Enable sign-on and read users' profiles". The 2nd column (Application permission) is not needed for this demo app.

The wording is completely different on the site, so I am not sure how to proceed.
