Issue: Feature Request – Add Notification Grouping Support

[rasel6999]

Currently, the upload notifications are displayed as separate bubbles for each upload, making it difficult to manage multiple uploads at once. I have tried multiple approaches, including customizing UploadNotificationConfig and manually handling notifications, but there is no built-in way to group them under a single notification.

Would it be possible to add support for notification grouping (group and groupSummary) in UploadNotificationStatusConfig? This would allow multiple uploads to be bundled into a single expandable notification instead of cluttering the notification panel with individual bubbles.

What I Tried
Setting custom notification IDs and manually managing notifications.
Attempting to modify UploadNotificationConfig, but there is no built-in grouping option.
Using NotificationCompat.Builder.setGroup() on Android, but since UploadService manages notifications internally, this is not effective.
Suggested Solution
Add a group parameter to UploadNotificationStatusConfig to allow grouping multiple upload notifications together.
Alternatively, provide a way to override the notification creation so that developers can customize grouping behavior.
References & Possible Implementation
If there is already a way to achieve this, could you please guide me in the right direction? I would appreciate any documentation, sample code, or workaround you can suggest.

Thank you for your time and for maintaining this great library! 🙏
