Inside a Service

@Injectable()
export class ReportsService {
  constructor(
    private readonly prisma: PrismaService,
  ) {}

  getSomething(id: number) {
    return this.prisma.aThing.findUnique({
        where: {
           id,
        }
    }
  }
}

In your app.module.ts

import { Module } from '@nestjs/common';
import { ConfigModule } from '@nestjs/config';
import { PrismaModule } from './prisma/prisma.module';
// Other imports

@Module({
  imports: [
    // global modules
    ConfigModule.forRoot({
      isGlobal: true,
    }),
    PrismaModule, // <== here
  ],
  providers: [{ provide: APP_GUARD, useClass: GlobalJwtGuard }], // relies on the AuthModule
  controllers: [AppController],
})
export class AppModule {}
