Configuring OAuth2 is based on depreciated azure interface

[ddt3]

Azure app registrations have changed, which makes it hard to follow the given instructions:

• "Name Your App and then click Create App" Should include the choice: "Accounts in any organizational directory (Any Azure AD directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox)"

• client secret needs to be copied during creation, it can't be done afterwards.

• "Under the section Authorization API add auth for" it is now called API permissions and it is not clear which api to add the permission to. (Microsoft Graph)
