How to get smart rule to act on tags created on documents

Here’s what I have

For clarification, the script code again

function performsmartrule(records) {
	var app = Application("DEVONthink 3");
	app.includeStandardAdditions = true;

	records.forEach (r => {
		if (r.type() === "tag") {
           app.logMessage(r.name());
        } else {
            app.logMessage(`triggered for document type ${r.type()}`);
        }
	})
}

And in DT’s log messages, I get “triggered for document type group”. Investigating further, the name property of this “group” is, in fact, what I entered as name for the new tag.
Is that what you were after?
The type of the new tag being “group” instead of “tag” seems a bit weird at first, but since the tag is shown to “contain” the record that has been tagged, that might be ok.
