Hi. I am using the signUp function to register users in (supertokens-web-js/recipe/emailpassword), but I don't want it to automatically log in the user after registration. In the first code block at this link: https://supertokens.com/docs/emailpassword/custom-ui/email-password-login, there's a line of code: // sign up successful. The session tokens are automatically handled by the frontend SDK. It seems like the SDK is automatically performing the login. How can I prevent this?
