Hello, i'm evaluating SuperTokens for Authentication/Authorization. I have a few questions:
1. I want to track the user that signed up in our db. How can I specify a specific user id when signing up or do I need to do this after in some callback after signup?
2. In the flows password reset /email verification, is it possible to intercept and send my own custom email? I want to customize and send the email myself.
3. Is it possible to wire up two frontends (nextjs) to one backend with one supertoken application?
