Sadly, the way to use Generics with forwardRef

component.tsx

interface Props<T extends unknown> {
  // ...
}

export interface MyFormRef<T extends unknown> {
  // ...
}

  
const MyForm = forwardRef(<T extends unknown>(props: Props<T>, ref: Ref<MyFormRef<T>>) => {
    // some component body here ...
});

export default MyForm as <T extends unknown>(props: Props<T> & { ref?: Ref<MyFormRef<T>> }) => JSX.Element;
