Resource Files: How to add containers folder into apk

Hi Ionic community! I have a question regarding resource-files. I added a resource file in my config.xml. <resource-file src="filename" target="assets/containers/filename" . The file is under my android assets container folder but when I run the ionic cordova build android the assets folder does not contain the containers folder in the APK. Is there’s something I’m missing with resources files and ionic cordova builds?

I think Files added via the resources File Tag are added to the platforms/android/app Folder. Do you find your assets Folder in there?
