Is the generator part of the prisma schema file needed for WG prisma datasource?

General
1

for PRISMA data source, we found that omitting the generator has no impact on the WG functionality.

generator client {
    provider = "prisma-client-js"
}
  • Is this needed?
  • Does WG using specific version of Prisma or it is WG interpretation of Prisma schema?
  • Which version of Prisma client is being used? We see loading PRISMA as loading the WG SDK, but prisma is missing from package.json file.
