Use prisma generated types with swagger nestjs

I am using nestjs with prisma and swagger. When I use

import {PrismaGeneratedType} from '@prisma/client';

...

@ApiOkResponse({type: PrismaGeneratedType})

in a controller if gives error:

'PrismaGeneratedType' only refers to a type, but is being used as a value here

since prisma generate types and not class definitions. How can I use Prisma generated client ( types ) with swagger ?
