See here to learn more.
create_channel	boolean	Determines whether to create a new channel if there is no existing channel that fits the specified target scope including `target_at` and `target_list`.

pause	Status changes from `running` to `paused`. This action pauses a running announcement.
resume	Status changes from `paused` to `running`. This action resumes a paused announcement to restart as soon as possible.
