Autocomplete: Support info message when no suggestion has been found

When autocompletion has been triggered explicitly (ctrl + space) and there’s no result to offer to the user I would like to show an info message giving feedback to the user that his action was performed. Is there currently a way to achieve that?

See for example vscode:


The autocomplete package doesn’t provide this, no. You may be able to bind the key that start completion to a command that both calls startCompletion and tells some view plugin that completion was started, and that it should, if completionStatus returns to null directly from "pending", it should show a tooltip.
