How do I make 'forgot password' working in react-aad-msal with Azure AD B2C?

What I did was create a Route in my App.js:

          <Route
            path="/forgot"
            component={() => {
              window.location.href = forgotPasswordUrl;
              return null;
            }}
          />

Then, in the constructor

if (window.location.hash.indexOf('AADB2C90118') >= 0) {
  history.push('/forgot');
}

And that works.
