Here is a 7

// smo119401 etc are notes
const smo119414 = new VF.Tuplet([smo119401,smo119403,smo119405,smo119407,smo119409,smo119411,smo119413], 
{"num_notes":7,"notes_occupied":4,"ratioed":false,"bracketed":true,"location":1});

That is just a parenthesis modifier. You add it directly to the note.

        note.addModifier(new Parenthesis(ModifierPosition.LEFT), 0);
        note.addModifier(new Parenthesis(ModifierPosition.RIGHT), 0);
