Not able to get cron jobs working (won't show up in dashboard)

import { cronJobs } from "convex/server";
import { internal } from "./_generated/api";

const crons = cronJobs();

crons.hourly(
  "fill missing book genres @ 0",
  { minuteUTC: 0 },
  internal.myFunctions.fillMissingBookGenres
);

export default crons;
