So in my flutter application i am sending notifications from my Golang Backend service using OneSignal REST API. In my app there are groups where people are chatting and those notifications i am sending. Now i want to implement two things

1. Clear all notifications of a group or thread when any one notification of the group is clicked.
2. Clear all notifications of the group if that group is opened directly and not from notification bar

now to implement this i am not being able to find the right sources. OneSignal's CANCEL MESSAGE endpoint does not seem to be too helpful here , neither am i able to fully understand how exactly to implement OneSignal's Mobile SDK's removeGroupedNotifications function. So i wanted help in implementing these two features, if anyone has any experience in implementing these?

• flutter
• notifications
• onesignal

Well,

• A notification is clicked -> Use removeGroupedNotifications(groupKey)
• The group is opened directly -> Call removeGroupedNotifications(groupKey)
• Remove all notifications (if not using groups) -> Use clearAll()

And, OneSignal REST API doesn't support clearing delivered notifications, use OneSignal's Mobile SDK for instant removal.
