How can I migrate users effectively? Currently, I don't have any active authentication services. I only collect data for my future users, storing their emails and other relevant information. Ideally, I would be able to iterate through the user data, creating new user accounts and adding their metadata, generating a random password and sending an email with a temporary email address and a link to activate the user's account. Based on the documentation, the only method I found so far involves making API requests and manually processing each request. Is there a more streamlined way to achieve this using the client? I'm working with Node and Fastify
