• The button for closing the chat and the button for activating the voice assistant are implemented as plain images rather than interactive elements.

• Because of this, users with motor impairments cannot move focus to these controls, making it impossible to activate them with the keyboard.

• This also complicates navigation for blind users, as screen readers do not treat these images as actionable elements.

Potential Improvement Considerations

Is it possible to implement these controls using the <button> element?

If replacing the elements is not feasible, could the existing images be enhanced by adding role="button" and tabindex="0" to ensure they are accessible and focusable?
