I am trying to connect my frontend reactjs app and backend nodejs app for registering and login using azure ad b2c with google as identity provider I did all settings as per this

After running the app the user is registering successfully but i am not able to store user information in my db using nodejs, I am not understanding how the flow works

the user information was stored in azure, but i would like hit one more node api which would fetch the data from azure and save it to my mysql db and then I give access to the application.

can anyone help me with this,

specifically i would like to know how this reply url works how could I hit my node api and after successfully saving info in db give access to my reactjs dashboard?

in react I used msal package
