Merges a new toast message into the current toast list.

toast_group/1 is just a small Phoenix.Component wrapper around the LiveComponent for toasts. You can use the LiveComponent directly if you prefer, this is just a convenience.

Attributes

• flash (:map) (required) - the map of flash messages.
• id (:string) - the optional id of flash container. Defaults to "toast-group".
• connected (:boolean) - whether we're in a liveview or not. Defaults to false.
