Oauth tokens with access to the Microsoft 365 Defender API

The procedure to create an application is found on the below link:

https://docs.microsoft.com/en-us/microsoft-365/security/mtp/api-create-app-web?view=o365-worldwide#create-an-app[Create a new Azure Application]

When giving the application the API permissions described in the documentation (Incident.Read.All) it will only grant access to read Incidents from 365 Defender and nothing else in the Azure Domain.

After the application has been created, it should contain 3 values that you need to apply to the module configuration.

These values are:

- Client ID
- Client Secret
- Tenant ID

Example config:

[source,yaml]
----
- module: microsoft
m365_defender:
enabled: true
var.oauth2.client.id: "123abc-879546asd-349587-ad64508"
var.oauth2.client.secret: "980453~-Sg99gedf"
var.oauth2.token_url: "https://login.microsoftonline.com/INSERT-TENANT-ID/oauth2/token"
----

*`var.oauth2.client.id`*::

This is the client ID related to creating a new application on Azure.

*`var.oauth2.client.secret`*::

The secret related to the client ID.

*`var.oauth2.token_url`*::

A predefined URL towards the Oauth2 service for Microsoft. The URL should always be the same with the exception of the Tenant ID that needs to be added to the full URL.
