I have added mannual MCP for datadog via cli works fine but when i tried with the desktop app on MACos got this error Authentication failed
datadog: RPC error -32603: Request session.mcp.oauth.login failed with message: failed to initialize MCP client: Send message error Transport [rmcp::transport::worker::WorkerTransport>] error: unexpected server response: HTTP 401 Unauthorized: {"errors":["Unauthorized"]}, when send initialize request

从 /chat 入口开始，在 macOS 桌面应用中复现 Datadog MCP 的手动设置，并将其与可正常工作的 CLI 配置进行比较。调查应用版本 1.0.21 在 session.mcp.oauth.login 期间报告的 401 Unauthorized 响应；当 Datadog MCP 在桌面应用中成功初始化且未发生身份验证失败时，即视为完成。
