Configuring an enterprise application in Azure Active Directory
Go to the Azure portal and navigate to Azure Active Directory.
Select the "Enterprise applications" option.
Click on "New application" to add a new enterprise application.
On the page for adding application, click on the "Create your own
application" button.
Enter the name of the application in the “What's the name of your app?”
field, select the "Integrate any other application you don't find in the
gallery (Non-gallery)" option, and then click on the “Create” button to add
the application.
The added application will be listed in the “Enterprise Applications” menu
along with other enterprise applications, if any. It is through this menu
that you will be able to locate your enterprise application whenever you need
to make configuration changes or view the provisioning log.
