How to choose a random message from an array for Firebase Cloud Messaging Campaign-CodePudding

I'm trying to build a campaign that sends a random message from an array of 10 or 100 messages every day. Currently, in Firebase, I'm able to create a daily campaign that sends the same message daily. Is it possible to use Cloud Functions to change the message of the campaign every day?

You can use Firebase Scheduled Functions that'll run at the interval that you specify. In the function you can add the array of N messages and then get a random item from array and send it via Admin SDK.

exports.scheduledFunction = functions.pubsub.schedule('0 0 * * *').onRun((context) => {
 
  const messages = [];

  // 1. get a random message from array
  // 2. send notification via FCM (Admin SDK)

  // terminate the function
  return null;
});
