I am scheduling notifications as follows -

```
FCM.scheduleLocalNotification({
fire_date: new Date().getTime(),
id: "UNIQ_ID_STRING",
body: "BODY",
show_in_foreground:true,
title:"TITLE"
});
```

However, I am not getting any notifications (which I should get immediately according to the value of **fire_date** set by me.

But when I run **presentLocalNotification**(), it immediately presents a notification.
```

FCM.presentLocalNotification({
fire_date: new Date().getTime(),
id: "UNIQ_ID_STRING",
body: "BODY",
show_in_foreground:true,
title:"TITLE"
});
```

What could be the problem here ? I tried to replicate this with the Example Repo but it worked there.
Are there any specific requirements to scheduling notifications ?
