 When you need to apply some decorators like `@Authorized`, `@UseMiddleware` or `@Extensions` on the generated resolvers methods, you don't need to modify the generated source files.
 
-To support this, `typegraphql-prisma` generates two things: `applyResolversEnhanceMap` function and a `ResolversEnhanceMap` type. All you need to do is to create a config object, where you put the decorator functions (without `@`) in an array, and then call that function with that config, eg.:

Remember that it has to be done before building the schema, eg.:

 This way, when you call `createCategory` GraphQL mutation, it will trigger the `type-graphql` `authChecker` function, providing a `Role.ADMIN` role, just like you would put the `@Authorized` on top of the resolver method.
