FCMPlugin is undefined in the app (but defined in the browser)

[freescout-helpdesk]

Using Phonegap. By some reason FCMPlugin is always "undefined" in the emulator and in the built app (but defined in the browser):

document.addEventListener('deviceready', function() {
    console.log(typeof(FCMPlugin)); // result: [console.log] undefined
}, false);

config.xml:

    <engine name="android" spec="^7.1.4" />
    <plugin name="cordova-plugin-inappbrowser" spec="~3.1.0" />
    <plugin name="cordova-plugin-whitelist" spec="~1.3.4" />
    <plugin name="cordova-plugin-fcm-with-dependecy-updated" spec="~4.1.0" />

Noticed, that in cordova-plugin-fcm-with-dependecy-updated is not mentioned in plugins/android.json (but mentioned in plugins/browser.json):

{
  "prepare_queue": {
    "installed": [],
    "uninstalled": []
  },
  "config_munge": {
    "files": {}
  },
  "installed_plugins": {
    "cordova-plugin-inappbrowser": {
      "PACKAGE_NAME": "net.freescout.app"
    },
    "cordova-plugin-whitelist": {
      "PACKAGE_NAME": "net.freescout.app"
    }
  },
  "dependent_plugins": {}
}

Adding it there manually does not help.

It does not work in the Phonegap emulator, but works in a built app!
