FCM Push to Telegram Channel Redirect without app launch

[Vanish404]

Hello everyone,

We're trying to achieve a specific behavior on Android (currently) and IOS for our React Native app:

Goal: Redirect users directly from an Mindbox (via FCM) push notification to a Telegram channel (or browser as fallback) without our React Native app launching/appearing.

What we've tried:

1. Using a custom FirebaseMessagingService to intercept FCM Data Payload (Mindbox sends data containing eventType: "navigate", target: "tg", link: "https://t.me/channel").
2. Creating and showing a custom notification.
3. Embedding a PendingIntent in this notification that directly launches an ACTION_VIEW Intent for the Telegram link (or browser fallback) with FLAG_ACTIVITY_NEW_TASK and FLAG_ACTIVITY_CLEAR_TOP.

Problem:
The push arrives, our custom notification appears, and clicking it correctly opens Telegram/browser. However, after that, especially upon returning from Telegram/browser, our React Native app's MainActivity still launches/comes to the foreground.

Question:
How can we ensure our React Native app does not launch/appear when handling such a deep link redirect from an FCM push notification on Android?

Thanks!
