title: Is it possible to trigger a FCM push notification based on an expiry date in Firestore Database?
body: <p>I am trying to build an Android app using Kotlin that sends a push notification to the user's device using FCM in Firebase when one of their items are expiring soon. However, I have not been able to figure out how to trigger the notification based on the expiry date stored in the Firestore Database for a specific item. In Firebase -&gt; Engage -&gt; Cloud Messaging -&gt; Notifications -&gt; New Notification, it seems like you can only schedule a notification based on a fixed date.</p>
  <p>Is there a way to trigger the notification based on a value stored in the Firestore Database instead?</p>
  <p>Logic should be:
  If current_date &gt; expiry_date then trigger push notification.</p>
  <p>Thanks in advance.</p>
