Zod object validator using Prisma (MySQL) enum

Hey, could anyone hint how to create a zod validator object, which one of the keys should be an enum from prisma (mysql)

model ProposalOption {
  id                Int                 @id @default(autoincrement())
  description       String              @db.TinyText
  category          OptionCategory
  active            Boolean
}

enum OptionCategory {
  reason
  size
  feature
  additional
}

model ProposalOption {
  id                Int                 @id @default(autoincrement())
  description       String              @db.TinyText
  category          OptionCategory
  active            Boolean
}

enum OptionCategory {
  reason
  size
  feature
  additional
}

zod validator (here is the issue, please help)

import z from "zod";
import type { OptionCategory } from "@prisma/client";

const options: OptionCategory[] = ["additional", "feature", "reason", "size"];

export const CreateProposalOptionValidator = z.object({
  description: z
    .string()
    .min(5, { message: "Description must have at least 5 characters" })
    .max(100, { message: "Description must have less than 100 characters" }),
  // @ts-expect-error TODO: fix this, just a string atm
  category: z.enum(options),
});

export type ProposalOptionCreateRequest = z.infer<
  typeof CreateProposalOptionValidator
>;

import z from "zod";
import type { OptionCategory } from "@prisma/client";

const options: OptionCategory[] = ["additional", "feature", "reason", "size"];

export const CreateProposalOptionValidator = z.object({
  description: z
    .string()
    .min(5, { message: "Description must have at least 5 characters" })
    .max(100, { message: "Description must have less than 100 characters" }),
  // @ts-expect-error TODO: fix this, just a string atm
  category: z.enum(options),
});

export type ProposalOptionCreateRequest = z.infer<
  typeof CreateProposalOptionValidator
>;

when parsing body on backend using this validator, category is just a string, which causes another type error on the backend when creating a new record pls help!
