Clear all notifications in the android notification tray

I'm sending multiple notifications to my app. What I want to achieve is whenever a user clicks one notification then all notifications in the notification tray disspear.

I've tried adding

`notification.android.setAutoCancel(true)`

which does the trick for only one notification (the one which is being clicked)

I've also tried:

`firebase.notifications().removeAllDeliveredNotifications() `

which doesn't have any effect.

How can I achieve this?

Here's my full code:

componentDidMount() {
firebase.notifications().removeAllDeliveredNotifications()

this.notificationDisplayedListener = firebase.notifications().onNotificationDisplayed((notification) => {
});

this.notificationListener = firebase.notifications().onNotification(async (notification) => {
// Process your notification as required
notification.android.setAutoCancel(true)
firebase.notifications().removeAllDeliveredNotifications()
}
async componentWillMount() {
this.notificationDisplayedListener = firebase.notifications().onNotificationDisplayed((notification) => {
});
this.notificationListener = firebase.notifications().onNotification((notification) => {
});

this.notificationDisplayedListener();
this.notificationListener();
}`

Start by reproducing the notification flow around firebase.notifications().onNotification and the calls to notification.android.setAutoCancel(true) and removeAllDeliveredNotifications(). Confirm the expected behavior on Android: clicking one notification should clear every delivered notification, and verify whether the current API calls produce that result.
