+// @ts-ignore forwardedAs is valid here but I don't know how to fix the typescript error
+const TabNavImpl = ({as, ...props}: TabNavProps) => <StyledTabNav forwardedAs={as} {...props} />


Instead of using @ts-ignore, consider using a proper TypeScript assertion or interface extension to handle the forwardedAs prop. This improves type safety and code maintainability.
