React TypeScript & ForwardRef - Property 'ref' does not exist on type 'IntrinsicAttributes

After dropping quite some time fighting with typings and forwardRefs in React and TypeScript, I am hoping somebody else can clear this up for me.

I am building a DataList component which is comprised of three pieces:

• Container to hold all event listeners and logic
• List itself, a ul
• List item, an li

Ultimately, the usage would look like this:

<DataList.List ...>
  <DataList.Item ...>content</DataList.Item>
</DataList.List>

To achieve the functionality I need, I am leveraging React.forwardRef, but have found this difficult with TypeScript as I struggle correctly typing the components to receive a ref as well as children and additional props.

DataListContainer
I essentially want this component to just handle logic and event listeners while returning the primary DataList component (shown next). But the key here, is that I need to create the DataList ref here and assign it to the returned component.

const DataListContainer: React.FC = ({ children }) => {
  const listRef = useRef<HTMLUListElement>(null);

  return (
      <DataList ref={listRef}>{children}</DataList>
  );
};

DataList
I want the DataList component to just handle its UI and props.

interface Props extends TestId {
  focusedItemId?: string;
}

const DataList: React.FC<Props> = React.forwardRef<HTMLUListElement, Props>(
  ({ children, focusedItemId, testId }, ref) => {
    return (
      <ul
        aria-activedescendant={focusedItemId}
        data-test-id={testId}
        ref={ref}
      >
        {children}
      </ul>
    );
  },
);

This isn't quite right, though. As This setup gives me the error

Type '{ children: any[]; ref: RefObject<HTMLUListElement>; }' is not assignable to type 'IntrinsicAttributes & Props & { children?: ReactNode; }'.
  Property 'ref' does not exist on type 'IntrinsicAttributes & Props & { children?: ReactNode; }'.
