React - Jest testing - TypeError: refetch is not a function

I'm using a useFocusEffect() hook in my component, which uses refetch from react-query. Code is working fine in the app. Issue I'm facing is with unit testing. I'm using Jest and getting an error that TypeError: refetch is not a function.

I've defined a mock function const refetchFunc = jest.fn(); and have provided it to refetch as a mockReturnValue, but still the error persist.

App.js:

const { data, refetch } = useStudents(
  student?.id
);

useFocusEffect(
  React.useCallback(() => {
    refetch();
  }, [refetch])
);

Jest Test:

import { Home } from './Home';

jest.mock('hooks/Auth/useLoadAuthStudentsData', () => ({
  useLoadAuthStudentData: jest.fn()
}));

jest.mock('hooks/Student/useStudents', () => ({
  useStudents: jest.fn()
}));

jest.mock('@react-navigation/core', () => {
  return {
    ...jest.requireActual('@react-navigation/core'),
    useNavigation: jest.fn(() => ({}))
  };
});

const useLoadAuthStudentsData = userHook as ReturnType<typeof jest.fn>;
const useStudents = tasksHook as ReturnType<typeof jest.fn>;

const navContext = {
  isFocused: () => true,
  addListener: jest.fn(() => jest.fn())
};

const mockParams = {
  params: {
    studentId: 'studentId'
  }
};
  
  describe('Home', () => {
  beforeEach(() => {
    const refetchFunc = jest.fn();
    useStudents.mockReturnValue({
      data: Student.deserializeAsList(studentsStub),
      isLoading: false,
      isSuccess: true,
      isError: false,
      refetch:refetchFunc
    });
    useLoadAuthStudentData.mockReturnValue({ data: studentStub });
  });

  const component = (
    <NavigationContext.Provider value={navContext}>
    <Home route={mockParams} navigation={{ goBack: jest.fn() }} />
    </NavigationContext.Provider>
  );

  it('should render app without error', () => {
    expect(render(component)).toBeTruthy();
  });

Error:

● Home › should render screen without error
