Unused imports IconButton, Tooltip.

Copilot Autofix

AI 10 months ago

To fix this problem, simply remove IconButton and Tooltip from the destructured import list from @mui/material on lines 13–23. No further changes to code, logic, or imports are necessary. The change should be made only in the import statement block at the top of the file (ui/src/components/EnhancedWebSocketStatus.tsx), specifically removing IconButton and Tooltip (making sure to preserve commas and formatting).
