I would like to use and be able to customize more than one helper in custom_helper. It is possible?

When WebDriverIO is the first one in codecept.json, only the chrome render the url, and if the Nightmare is the first one, the url is rendered only in Electron.

I am create a custom helper and I using something like this:

testCustomHelperWithNightmare(var1, var2) {
this.helpers['Nightmare'].fillField(var1, var2);
}
testCustomHelperWithProtractor(var1, var2) {
this.helpers['Protractor'].fillField(var1, var2);
}

My codecept.json:

{
"output": "./output",
"helpers": {
"WebDriverIO": {
"url": "http://www.google.com.br",
"smartWait": 5000,
"browser": "chrome",

"windowSize": "maximize",

"acceptInsecureCerts": true,
"chrome": {
"browserName": "chrome",

"platform": "ANY",

}
}
},
"Nightmare": {
},
"Protractor": {

"TestCustomHelper": {
"require": "./testcustomhelper_helper.js"
}
....
}
