I may be late to answer this question but it might help others in the future.

in my case, I needed to send a notification on a specific date and time.

I used node-schedule which is a flexible cron-like and not-cron-like job scheduler for Node.js.

start with importing node-schedule

const schedule = require('node-schedule');

then scheduling push notification as below

schedule.scheduleJob(
  `${pushNotification._id}`, //Job name, prefered to be unique 
  scheduledDate, // 2020-05-02T12:52:00.000Z
  async () => {
    await FCM.broadcast({
      topic: 'topic_name',
      title: 'sample title',
      body: 'sample body',
      imageUrl: 'image url sample',
    });
  }
);

and in case you want to cancel the job

schedule.cancelJob('job_id');

and in case you want to reschedule the job

schedule.rescheduleJob('job_id', 'scheduleDate');

hope this would help.
