When you add SweetAlert2 dialogs to your React app, it's essential to consider accessibility so that all users, including those who rely on assistive technologies, can interact with your alerts. SweetAlert2 provides several built-in accessibility features, such as ARIA attributes for dialog roles and labeling, which help screen readers correctly announce the content and purpose of each alert. However, you should still review your dialog content to ensure that it is concise, descriptive, and free from unnecessary jargon. Always provide meaningful titles and clear instructions, and avoid using only color to convey important information, as this may not be perceivable by all users.

To create a truly user-friendly and accessible experience with SweetAlert2, you should follow best practices for timing, focus management, and keyboard navigation.

• Make sure that when a dialog appears, focus is automatically moved to the alert;
• Ensure users can navigate all interactive elements using only the keyboard;
• Support the Tab key for moving between buttons or input fields;
• Allow users to dismiss dialogs with the Escape key;
• Avoid auto-closing alerts unless absolutely necessary, and if you must use them, provide enough time for all users to read and respond.

After the alert is dismissed, return focus to a logical place in your app, such as the button that triggered the alert, to maintain a smooth navigation flow.
