How to use the @entando/utils.convertToQueryString function in @entando/utils

onSubmit: (values) => {
    dispatch(fetchDataModelListPaged({ page: 1, pageSize: 10 }, convertToQueryString({
      formValues: values,
      sorting: {
        attribute: 'code',
      },

  },

    });
    dispatch(fetchSearchPages({ page, pageSize: 5 }, queryString));
  },
});

const applyFilter = (filter, paginationMetadata) => (dispatch, getState) => {
  const selectedCategory = getSelectedDECategory(getState());
  dispatch(setDEFilter(filter, selectedCategory));
  const filters = getDEFilters(getState());
  const params = filters[selectedCategory] ? convertToQueryString(filters[selectedCategory]) : '';
  return dispatch(fetchDEComponents(paginationMetadata, params));
};

const generateQueryString = (values) => {
  const newValues = { ...values };

    formValues: newValues,
    operators: FIELD_OPERATORS,
    sorting: {
      attribute: 'username',
    },
  }).concat(withProfile);
};

const getFilteredContents = (formState) => {
  const filter = toFilter(formState);
