hi folks, 
I'm a bit confused by supertokens usage and can use some help to clarify my concepts.
so, I'm using managed service to store user session and password info but how can I create a copy of this user in my own database? 
do we get any callback or something with supertokens id?

There should be a “post login operation” section in the docs (on the left nav)

And in there, you will find post sign up page

Which will show you how to use our override feature to do whatever you like in there
