Issue requesting for a new token using refresh token

Hi,

I am using a springoauth2client library-based BFF application for authenticating my Angular app using Azure AD.
I have registered my application as a web App in Azure with a custom scope and the login works fine. When I add offline_access to the scope, I am also able to get the refresh token.
But the problem is when the access token expires and the spring oauth2 client tries to use the refresh token to fetch a new Auth token, the request fails with the following error :

[2023-09-27 16:09:51.080][sessionId][DEBUG ][org.springframework.web.client.RestTemplate.debug:127] - HTTP POST https://login.microsoftonline.com/XXXXX/oauth2/v2.0/token

This scenario is supported only if resource is specified using the GUID based App Identifier.

Please let me know what needs to be changed. I am assuming I am missing something during App Registeration since this is a federated client and I am not facing any such issue with other Identity Providers

リポジトリのファイルやテストは指定されていません。まず、Spring OAuth2 クライアントの refresh token フローと、ログに記載されている Azure AD v2 /token リクエストを追跡します。アプリケーション登録およびクライアント設定を失敗しているリクエストと比較し、その後、期限切れの access token を正常に更新できることを確認します。
