cannot find WebDriverAgent from ApplicationsAppiumappContentsResourcesappnode_modulesappium

Following Training 11, part 3:
I don't have node_modules under
/Applications/Appium.app/Contents/Resources/app/node_modules/appium, so there is no way to get WebDriverAgent there.

But I found WebDriverAgent on different path:
/Applications/Appium.app/Contents/Resources/app/node_modules/appium-xcuitest-driver/WebDriverAgent

Is this a new file structure for Appium Desktop?
May I able to use this WebDriverAgent?  
Thanks
