How to get user_id from Neon_Auth table using Drizzle schema?

My project is Next.js, Drizzle, Neon, and Neon Auth. I am trying to create my drizzle tables for neon. When creating my users table I want to get the user_id for each user from the Neon Auth table so they are connected. Can you help me understand how to do this, or provide me a link to the documentation that talks about this? Thanks.
