研究方向: Investigate the implementation of the 'Respect System Focus Mode' feature in the Windows notification handler. Check code in the `Telegram` or `Platform/Windows` directories for how system focus assist is queried. Look for any existing calls to `ShouldAppsUseToastNotification` or similar APIs. Also verify if there are version specific checks for Windows 10 that might be missing.
