Changing the method name from "triggerMessage" to "displayActionMessage".

Generally speaking, I like to call the message at the bottom an "action message".
And things can "trigger" it, but in the case of a method that actually proactively displays the message, I find "displayActionMessage" to be a better name.

Also, removing package-lock files and improving code style
