How do list all applications in Graph Explorer with my Azure free account? - azure

Question

I want to learn Azure directory services, so I created a free Microsoft Azure account to play around with Azure, and then I created a new App registration at portal.azure.com. So I have this registered application in Azure with a Client ID, Tenant ID, and even a Client Secret, because I want to learn API permissions with this app.
Now in the Microsoft Graph Explorer, I want to try using API methods like Get Application and List Applications.
However, if I log in and run the API to list my applications (GET https://graph.microsoft.com/beta/applications), the response has an empty array of applications.
Also if I try to GET the specific app that I registered in AD, I get a 404: Resource Not Found found error.
What am I doing wrong? How can I use the Graph Explorer with my test Azure account so my registered application can be retrieved and edited with Microsoft Graph APIs?
More Details Below
When I run GET https://graph.microsoft.com/beta/applications in Microsoft Graph Explorer, I expect a list of my applications, including the one app I registered in Azure. Instead, here is the response:
{
"#odata.context": "https://graph.microsoft.com/beta/$metadata#applications",
"value": []
}
When I run GET https://graph.microsoft.com/beta/applications/{client-id}, with my registered app's client-id, I expect all the details of my registered app, but instead, the response is error 404:
{
"error": {
"code": "ResourceNotFound",
"message": "Resource not found.",
"innerError": {
"request-id": "*****",<--I commented this out
"date": "2019-05-28T20:17:11"
}
}
}
If this were a permissions issue, I would expect unauthorized errors instead of "resource not found". I've tried adding Microsoft Graph permissions to my registered App (Directory.Read.All, Directory.ReadWrite.All), but this hasn't helped.

This is nothing to do with Azure free account. If you login in Graph Explorer using outlook account, it will identify this account as a personal account(with tenant outlook.com). That's why you can not find the applications you created in your tenant.
It is recommended to create a new user in your tenant to do the tests.
Here are the steps.
1.Click Azure Active Directory->Users->New User. The username should be something like username#{your tenant name}(XXX.onmicrosoft.com)
2.After the creation, add the roles for this user.
