Schema introspection fails without hasura admin secret

[DVGY]

If I don't provide hasura admin secret, the query fails for introspection. I read that admin secret should not be sent via client side app.

Is this true or I am doing something wrong ?

function App({ msalInstance }: AppProps) {
  const [dataProvider, setDataProvider] = useState<DataProvider | null>(null);

  useEffect(() => {
    const buildDataProvider = async () => {
      const dataProvider = await buildHasuraProvider({
        clientOptions: {
          uri: 'http://localhost:8080/v1/graphql',
          headers: {

            Authorization: `Bearer ${getBearerToken(msalInstance)}`,
            // 'X-Hasura-Admin-Secret': envs.hasuraAdminSecret,

            'X-Hasura-Role': 'gc',
          },
        },
      });
      setDataProvider(() => dataProvider);
    };
    buildDataProvider();
  }, []);

  if (!dataProvider) return <p>Loading...</p>;

  return (
    <MsalProvider instance={msalInstance}>
      <Admin
        dashboard={Dashboard}
        dataProvider={dataProvider}
        authProvider={authProvider}
        i18nProvider={i18nProvider}
        layout={CustomLayout}
        loginPage={MSALLogin}
      >
        <Resource name={Resources.USERS} list={ListGuesser} />
        <Resource name={Resources.PROJECTS} list={ProjectList} />
      </Admin>
    </MsalProvider>
  );
}

export default App;
