To send inbox notification programmatically for a user we can do as below.
ResourceResolver resourceResolver = resolverFactory.getResourceResolver(null);
InboxNotification inboxNotification = inboxNotificationSender.buildInboxNotification();
inboxNotification.setAssignee("admin");
inboxNotification.setTitle("Page Published");
inboxNotification.setMessage("The page has been Published");
inboxNotificationSender.sendInboxNotification(resourceResolver, inboxNotification);
Is there any way we can send inbox notification to a group programmatically? I tried sendInboxNotifications but it is not happening.
