Could you share your implementation that how to use a silent push notification in widget extension?

Could you please share the implementation that how you receive silent push notification in widget extension and the test payload?

Thx However, CSA repo: https://github.com/project-chip/connectedhomeip can support above from 15.4.

this api is @available(iOS 17.0, tvOS 17.0, macOS 14.0, watchOS 10.0, *) public func containerBackground

APPGroups could help.

I use IPC notification(CFNotificationCenterPostNotification) and NSNotificationCenter to notify, then use App Group to share data between app and extension.
