Step 6 - Enter the URI in the Redirect URI section as a Web type link
Step 7 - In the second box under Redirect URI enter the address from step 7
Step 8 - Click "Register"
Step 9 - Select the application registration you just created.
Step 10 - Look at the "Essentials" section of the application screen
Step 11 - Record the Application (Client) ID from the Essentials section.

Step 13 - Add a permission for "Azure Active Directory Graph" from the Supported legacy APIs section.
Step 14 - Select "Delegated Permissions" and add the "Delegated:" permissions listed in the guide for step 14, then select "Applications Permissions" and add "Read Directory Data"
Step 15 - Click "Add Permissions"
Step 16 - Click "..." On the Azure Directory Graph permission group and Grant all permissions. All permissions should show a green check and "Granted" under their status when this is completed correctly.
Step 17 - in the left menu select "Certificates and Secrets"
Step 18 - Select "New client secret" and add a description for the new client secret.
Step 19 - Choose an expiration time for the new client secret.
Step 20 - Click "Add"
NOTE: When the secret is created you must copy the value to a text file at this time. Leaving this screen and coming back will obscure the value which is needed in later steps. To get a new value a new secret must be created as the value is only shown at the time of creation. Do not forget to copy this value.
