INVESTIGATE: Does notification panel (not tray) in right sidebar exist in a plugin?

[ayub02]

This ticket is to answer a following questions about the notifications (upsell) panel in right sidebar:

1. Notification panel should exist within a plugin slot. Was that plugin slot created?
2. If so, was the upsell panel moved into the slot?

Context
There are two key components: the NotificationsDiscussionsSidebarSlot and the NotificationsDiscussionsSidebarTriggerSlot. These allow for the customization of the right sidebar panel and the corresponding icon. By default, these slots display the entire right panel (combining Notifications and Discussions into one sidebar) along with the associated icons, without requiring any additional configuration. However, for the current use case, these slots are not applicable.

In this context, there are two types of sidebars: the Sidebar and the New Sidebar. The isNewDiscussionSidebarViewEnabled waffle flag is used to determine which layout should be displayed.

Sidebar

1. The Sidebar features notifications and discussions icons displayed side by side, with each panel opening independently. The NotificationTraySlot is utilized for customizing the content of the notification panel, which still has an associated trigger icon and window.
2. 

New Sidebar

1. The New Sidebar features only one icon, and the notifications and discussions panels are vertically stacked.
2. There is a NotificationWidgetSlot available for customizing the notification panel content. However, the external border and padding of the notification panel will remain intact, as this slot serves the same purpose as changing the notification panel's content.

Conclusion
Currently, there is no slot available that allows for independent configuration of notifications within the right sidebar.
