How to display device permission errors in a custom video or audio call app built with Daily

The tutorial discusses how to handle device permissions in video and audio-only calls within a custom Daily app built with SvelteKit, focusing on the 'camera-error' event triggered by Daily when there's an issue accessing devices such as cameras or microphones. The app displays an error message to users, providing instructions on how to resolve the issue, and includes a "Try again" button that clears the error state once permissions are updated.
