Hey, Is there a way to activate / deactivate the Login / Registration and give the user the option to skip it using the nextjs library? Here is a quick overview of the ordering process on our website: 1. Select a course 2. view course details 3. if the course requires an user account, show supertokens if not, skip 4. Enter personal details and complete the order. And is there a way to implement this using magic links alongside our existing backend with email / password auth? We are using selfhosted supertokens.
