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

Start from the /chat entry point and reproduce the manual Datadog MCP setup in the macOS desktop app, comparing it with the CLI configuration that works. Investigate the reported 401 Unauthorized response during session.mcp.oauth.login for app version 1.0.21; done means the Datadog MCP initializes successfully in the desktop app without an authentication failure.
