And Being too loud as 1 String.

Try this.

GenericArguments.remainingJoinedStrings(Text text);

Edit:
You may also get some extra mileage by using common reasons in the suggestions as tab.

GenericArguments.suggestions()

As for command syntax, you can surround long strings that aren’t remainingJoinedStrings with quotes, e.g. /e name "being too loud".
