Type of client extended with dynamic extensions

Hi! In Prisma docs they say that to get type of extended client we can use factory function and ReturnType utility as follows:

function getExtendedClient() {
  return new PrismaClient().$extends({
    /* extension */
  })
}

type ExtendedPrismaClient = ReturnType<typeof getExtendedClient>


And this work fine but how I can get client type when the set of extensions is dynamic? I mean the case when extensions are provided as argument to factory function and it cannot by tell explicitly what extensions are ther?

function getExtendedClient(extensions: NeedType[] = []) { // missing type for extension
  return extensions.reduce((client, extension) => client.$extends(extension), new PrismaClient()); 
}

type ExtendedPrismaClient = ReturnType<typeof getExtendedClient> // won't work


Is this possible to handle such a case with Prisma and TypeScript?
