Zod one or more values from an array

Thanks in advance, my mind has gone blank and I just cannot think at this point. How can I say with zod I want to have at least one value of these array of possible values passed through. So basically a multi select picklist.

probably with refine

import { z } from 'zod'

const arr = ['b']

const schema = z
  .array(z.string())
  .refine((val) => val.every((v) => arr.includes(v)), {
    message: 'Array element not in valid array'
  })

const payload = ['b']

const result = schema.safeParse(payload)

console.log(result)

import { z } from 'zod'

const arr = ['b']

const schema = z
  .array(z.string())
  .refine((val) => val.every((v) => arr.includes(v)), {
    message: 'Array element not in valid array'
  })

const payload = ['b']

const result = schema.safeParse(payload)

console.log(result)

with valid payload

{ success: true, data: [ "b" ] }

{ success: true, data: [ "b" ] }

with invalid payload

{
  "success": false,
  "error": {
    "issues": [
      {
        "code": "custom",
        "message": "Array element not in valid array",
        "path": []
      }
    ],
    "name": "ZodError"
  }
}

{
  "success": false,
  "error": {
    "issues": [
      {
        "code": "custom",
        "message": "Array element not in valid array",
        "path": []
      }
