Configuring a staging and production database in prisma.schema on Netlify

Howdy. I’m on netlify and want to be able to have a separate DB for Production and one for Staging (What Netlify would call deploy-preview or branch deploy) in struggle town at the moment.

I have tried to use this plugin that seems to run successfully, but the changes don’t seem to be applied to the prisma.schema and instead the default is used.

I have seen this plugin by @rob and was thinking about using that as a base to attempt another plugin for dealing with this problem.

But before iI go down that road, has anyone else had/solved this issue?
