• Make sure to select:
  Accounts in any organizational directory (Any Azure AD directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox)

• For Redirect URL (optional) add the following URL http://path/to/nextcloud/index.php/settings/user/externalstorages (Replace http://path/to/nextcloud/index.php with you valid Nextcloud installation path, ensure that you don't leave index.php in the path. Example: https://nextcloud.myserver.com/settings/admin/externalstorages)
• Click Register to create your app.

Add client secret

• Under the section Certificates and secrets add new client secret, Name, choose expires:never.
  Make sure to copy the created key (you will not be able to do that later on). Key needs to be pasted in Nextcloud in last step

Add permissions to app
