Specify the Description, Directory, Application ID, Application Key and Refresh Token.
To set the Refresh Token, click on "Request Refresh Token". A dialog will be displayed where you can request a code. Copy the generated code into the clipboard and return to the dialog. Paste the copied code into the input field. The code will be converted into a Refresh Token.
For the Application Key you need a valid Microsoft account and must provide access to Microsoft OneDrive via the Microsoft Application Registration Portal.
Create an OAuth 2.0 Application in Microsoft:
1. To create a Microsoft Application, open App registrations https://portal.azure.com/#blade/Microsoft_AAD_RegisteredApps/ApplicationsListBlade and click on "New registration" on top left of the page.
2. On the next page, choose an "Application Name" and since the Report-Server uses the "common"-tenant, we need to at least select one Multitenant option.
3. After registering the Application, you will be redirected to the overview of your application. Here the "Application (client) ID" is the OAuth Client-ID.
4. To generate the secret, go to "Certificates & secrets" and add a new client secret with "New client secret". The generated Secret will be displayed in the List below.
