Help on Applying Schema Changes from Branch to Main in Neon DB

Hi, I’m working on a project and was using the main branch in Neon DB. However, I needed to make some major schema changes, so I created a new branch and worked on those changes there. After completing the schema updates and generating the migration files locally, I want to apply all the changes from the new branch to the main branch. Could you please guide me on how to do this? Thank you!
