I am currently using expo to develop an app. I'm currently prompting the user to enter a time they want a notification to be sent to them. I take that time and save it in firestore. I'm currently able to access the time with

db.collection("users")
    .doc(auth.currentUser.uid)
    .get()
    .then((doc) => {
      return doc.data().time;
    });

my issue is now using that data in expos notification function inside the trigger

Notifications.scheduleNotificationAsync({
    content: {
      title: "App",
      body: "Daily Reminder",
    },
    trigger: {
      hour: "",
      minute: "",
    },
  });

Im trying to put the returned value inside the hour and minute from the db but it doesn't seem to be working. The .then() returns a promise and i'm not sure how to handle it. I tried changing the .then() to async and await but still having trouble.
