4Placing the Announcement Host

Announcements only appear where the Announcement Host is. Put it on every page where you want them seen — or once in the utility bar of an app, which covers all of its pages.

In Lightning App Builder, search for Announcement and drag Announcement Host onto the page. It has no property, takes no room, and shows nothing until a reader has an announcement waiting. It then puts a card at the bottom right of the screen, with Read and Later.

Lightning App Builder on an account record page, the component list filtered on Announcement, Announcement Host under Custom - Managed — In Lightning App Builder, drag **Announcement Host** onto the page, then save — and activate the page if it is not active yet.

Where	Behaviour
Utility bar	The usual choice. Add it as a utility item and tick Start automatically: it then covers every page of the app, list views included, without anyone opening it.
Record page	For announcements about one object, such as cases.
Home page	Reaches people as they start their session.

A page carrying the host twice — on the page and in the utility bar — still shows one card. An announcement placed in a given application (section 7) only appears where that application carries the host.

The Announcement Host card at the bottom right of a reader's home page, offering Read and Later — What a reader sees: the card, with *Read* and *Later*.

Read opens the announcement in a window, its pages on the left and the questions on the right. Later puts it off for an hour. Once opened, an announcement is not offered again, unless it is Critical and was not closed, or asks for a confirmation the reader has not given. When several are waiting, Critical ones come first, then the one never shown, then the one shown least recently.

The reading window: the page on the left, the Questions panel on the right, Previous and Next below — The reading window.
