How to run the codecept+appium in saucelab cloud devices

Hi,
How do i run the codecept project in saucelab device cloud?
I used the below details in the codecept.json file but failed to run in cloud.

“helpers”: {
“Appium”: {
“url”: “https://eu1.appium.testobject.com/wd/hub”,
“user”: “my_username”,
“testobject_api_key”: “my_testobject_api_key”,
“platform”: “Android”,

  "desiredCapabilities": {
    "smartWait": "5000",
    "deviceName": "Motorola_Moto_E_2nd_gen_free",
    "appPackage": "app.package.com",
    "appActivity": "app.package.com.activity.SplashScreenActivity",
    "newCommandTimeout" : "60"  
  }
}

}
