過往都使用傳統的.Net framework做開發, 這次手上拿到一個新專案想嘗試一些不一樣的

IDE工具: Visual Studio 2022
採用 React.js + .Net 6

在導入Windows驗證機制的時候出現問題, 參考microsoft和網路其他大神的解法卻還是有些問題, 認為是自己對於前後端架構的理解有誤
https://learn.microsoft.com/zh-tw/aspnet/core/security/authentication/windowsauth?view=aspnetcore-6.0&tabs=visual-studio
在Program.cs加上Windows驗證的設定，並切換IDE的模擬環境至IIS Express後
專案可以正常運行

但在fetch後端api的時候出現401.2的Error

如果直接在URL上面輸入https://localhost:*****/weatherforecast
則可以成功打到後端controller，並取得Windows驗證的身分資訊
若不啟用Windows驗證的話，專案就可以正常的打到後端controller並取得資訊

想請教是哪個部份的專案設定錯了呢?
謝謝

-以下是專案目前的部分程式碼-
