Function step_title
pub fn step_title(entry: &ActionContext) -> Option<String>Expand description
What one step did, said without anything it carried: an action by its
published label (“Post a message”), never through an app’s message,
which may quote an argument (the words of the message posted). What
someone is doing is told to everyone here, and their words are not.
None when the entry says neither what it did nor why.
