Ionic 4 / Capacitor / Cordova - Diagnostic Plugin and config.xml

I am trying to use the Ionic Native/Cordova Diagnostic plugin with Capacitor. By default diagnostic installs a lot of modules that I don’t need ( Contacts, calendar etc ). In their github page [ link ] they mention that we can add

<preference name="cordova.plugins.diagnostic.modules" value="[list of modules]" />

in config.xml.

First problem for me is capacitor does not have config.xml. I tried to create a config.xml in the root of the app and added the tags but it did not work.

I have been trying to do this the right way, on deploying the app store throws a lot of warnings regarding declaring variables in the info.plist file ( i know adding will solve it ) but i am not sure why i have to add so many modules and where to add the config to limit it.

Any help is appreciated. Thank you.
