Is @@fulltext feature can be used?

generator client {
  provider = "prisma-client-js"
  previewFeatures = ["fullTextSearch","fullTextIndex"]
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

model Category {
  id            String @id @db.Uuid @default(dbgenerated("gen_random_uuid()"))
  name          String
  companions    Companion[]
}


model Companion {
  id            String @id @db.Uuid @default(dbgenerated("gen_random_uuid()"))
  userId        String
  userName      String
  src           String
  name          String @db.Text 
  description   String
  instruction   String @db.Text
  seed          String @db.Text

  createdAt     DateTime @default(dbgenerated("now()"))
  updatedAt     DateTime @updatedAt

  category      Category @relation(fields: [categoryId], references: [id])
  categoryId    String

  @@index([categoryId])
  @@fulltext([name])
}
