Login failed in Incognito window in chrome

Hey,
I have added a custom domain as per a few comments in the auth0 community team.
Still, I’m facing a login issue in the incognito window.
What else could I be missing here? Please let me know.

Then added the domain here

    <Auth0Provider
      domain='auth.ubiquitousinfluence.app'
      clientId={getAuth0Creds().clientId}
      authorizationParams={{
        redirect_uri: window.location.origin,
        connection: 'email',
        scope: getAuth0Creds().scope
      }}
    >
      <ApolloProvider client={apolloClient}>
        <CustomContexts>
          <BrowserRouter>
            <RoutesMain />
          </BrowserRouter>
        </CustomContexts>
      </ApolloProvider>
    </Auth0Provider>
