I can reproduce your problem, you have to add the redirect URL under the **web** (not single page application). After that, you will be able to use the [auth code flow](https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow#request-an-authorization-code) to get the **code**.
