Banners are hidden by default, use [property@Banner:revealed] to show them.

Banners have a title, set with [property@Banner:title]. Titles can be marked
up with Pango markup, use [property@Banner:use-markup] to enable it.

The title will be shown centered or left-aligned depending on available
space.

Banners can optionally have a button with text on it, set through
[property@Banner:button-label]. The button can be used with a `GAction`,
or with the [signal@Banner::button-clicked] signal. The button can have
different styles, a gray style and a suggested style.
