Worked on the twentyhq/twenty repository to resolve a critical permissions gating issue affecting the APIs & Webhooks settings page. Addressed discrepancies between navigation and route protection by restructuring the SettingsRoutes.tsx file, ensuring that users with API_KEYS_AND_WEBHOOKS permissions could access the correct settings without being redirected. Utilized React and TypeScript to implement and validate permission-based access across multiple user scenarios, including targeted tests for various permission combinations. This fix improved the reliability and predictability of the settings access flow, reducing user friction and support overhead while maintaining consistent navigation for API keys and webhooks management within the front end.
