How do I use two-finger zoom in Appium / webdriver-io - appium

Question

I'm new to mobile automation, but not new to automation in general (worked with web). I'm building an automation where a two-finger zoom is required. I've looked through documentation trying to find a solution, and can't find one. There is Multi-Touch, but it's a misnomer because it seems to implement many different touches with one finger only in quick succession. Something like this doesn't appear to work:
client.touchMultiPerform([
[{ action: 'press', options: { x: 300, y: 100 } },
{ action: 'moveTo', options: { x: 100, y: 100 } },
{ action: 'release' },
],
[{ action: 'press', options: { x: 330, y: 100 } },
{ action: 'moveTo', options: { x: 400, y: 100 } },
{ action: 'release' },
],
]);
This does the first touch action, then the second touch action. Is there a method that allows this? Maybe a plugin? Or am I just not understanding a remarkably simple solution?
Here's a more complete example of what I've built:
var webdriverio = require('webdriverio');
var expect = require('chai').expect;
var config = require('./helpers/desiredCapabilities').options;
var client = webdriverio.remote(config);
describe('Android Script Testing', function () {
before(function () {
this.timeout(5000);
return client.init();
});
afterEach(function(){
this.timeout(5000);
});
it("should just click on things",async function(){
this.timeout(0);
client.click("#selectRegionButton")
client.waitForVisible("#Account", 5000).click("#Account");
client.touchAction(
[
[{ action: 'press', options: { x: 300, y: 100 } },
{ action: 'moveTo', options: { x: 100, y: 100 } },
{ action: 'release' }],
[{ action: 'press', options: { x: 330, y: 100 } },
{ action: 'moveTo', options: { x: 400, y: 100 } },
{ action: 'release' }],
]);
});
});

I'm not sure you are using Appium here, but if there is Appium in use then zoom and pinch will only work with Espresso Automation name in the desired capabilities.
Same is confirmed here and I have also tested the same using Espresso Automation name in Appium Java binding.
Try using the same automation name and your code should work.
Also, you have used client.touchAction in your code, instead use client.touchMultiPerform.
