How do you change the number of beats per measure with EasyScore?

How do you change the number of beats per measure/stave with EasyScore? I'm trying to change the voice to 3 beats per measure/stave. It looks like EasyScore.voice() has an optional second parameter with a 'time' option similar to the one the Voice object constructor has which might let you set the beats per measure but I can't figure out how to use it. (Stave.addTimeSignature() adds an image of a time signature but doesn't actually change how many beats are in a measure.) Here is my attempt based off of the first example in the EasyScore tutorial but I get an error saying the voice does not have enough notes. Thanks

const { Factory, EasyScore, System } = Vex.Flow;

const vf = new Factory({
  renderer: { elementId: 'output', width: 500, height: 200 },
});

const score = vf.EasyScore();
const system = vf.System();

system.addStave({
  voices: [score.voice(score.notes('C#5/q, B4, A4'), {num_beats: 3, beat_value: 4})]
}).addClef('treble').addTimeSignature('3/4');

vf.draw();

Nevermind I figured it out. Use {time: '3/4'} as the second option. You can also use EasyScore.set({time: '3/4'}) to set it as the default for all new voices created by EasyScore.

const { Factory, EasyScore, System } = Vex.Flow;

const vf = new Factory({
  renderer: { elementId: 'output', width: 500, height: 200 },
});

const score = vf.EasyScore();
const system = vf.System();

system.addStave({
  voices: [score.voice(score.notes('C#5/q, B4, A4'), {time: '3/4'})]
}).addClef('treble').addTimeSignature('3/4');

vf.draw();
