How to get drizzle-kit to connect to local supabase via websockets with neondatabase/serverless to

Hi,

I am working on an app that I plan to deploy to Cloudflare. I read that neondatabase/serverless is the proper driver to connect a postgres database from that environment.

I am migrating over from Prisma, and I want to introspect my current schema with drizzle-kit pull so I don't have to build it up myself.

When I run drizzle-kit pull, I keep getting this warning: Warning '@neondatabase/serverless' can only connect to remote Neon/Vercel Postgres/Supabase instances through a websocket, which results in an error:

Reading the 
drizzle.config.ts
 documentation, I can't seem to find where or how to set the driver. The section on driver only provides three options, but I don't see anything specific to neon.
