+プロバイダーの設定をすることで、ログインしていないユーザーに特定の制限を設定できます。

+    redirect?: string;
+    function?: () => void;
+    children?: React.ReactNode;
+  };

+制限したい要素の親要素に、`ScratchAuthProvider` を設置してください。

+import ScratchAuthProvider from "@scratch-auth/nextjs/src/components/provider";
+
+export default function DashboardLayout({
