Seeding not working in prisma.config.ts

Our CLIs have been screaming at us for a while, to upgrade from the package.json "prisma: {}" property, to the prisma.config.ts file. With this message: 
warn The configuration property `package.json#prisma` is deprecated and will be removed in Prisma 7. Please migrate to a Prisma config file (e.g., `prisma.config.ts`).
For more information, see: https://pris.ly/prisma-config

Currently we have both in our codebase, here's our package.json entry: 
  "prisma": {
    "schema": "packages/db/prisma/schema",
    "seed": "pnpm exec tsx packages/seed/src/index.ts"
  },
  "prisma": {
    "schema": "packages/db/prisma/schema",
    "seed": "pnpm exec tsx packages/seed/src/index.ts"
  },
This works fine. I can run pnpx prisma db seed and it executes this seeding. However, if I move the seeding to the prisma.config.ts, it no longer works. It simply just says "Environment variables loaded from .env" and then immediately exits, as if it found no script. I should note we are in a monorepo, and this prisma: { ... } block is in the root package.json, but the prisma.config.ts file is located close to prisma, in the packages/db folder. I would like to be able to run the pnpx prisma db seed script from root, and have it run the correct seed script, same as I am able to today. I have also tried various variations of the path in the seed script, to ensure I was pointing to the correct folder. Even if I just print a simple logging script like pnpm why prisma it isn't running. Is there any reason this couldn't work from the config, when it works from the prisma property in package.json? I should note it does work if I first navigate to the db package, and run the prisma db seed script from there, but I'd really avoid having to that, if at all possible.
