How do I add My facebook App ID Ads for Admob mediation

Hello Everyone,

I'm new to this forum, and to construct 2 as well . I just lunch my first game, and I need your help guys. I'm doing Admob mediation for facebook audience network. I got all the required things that Facebook audience network need. Google Play Package Name, Class Name, and Key Hashes. I find a way to get all theses, but the problem is that facebook asking for "Send Ad Request" which means that I need to put my App ID with in my Project in some way, so my app get connected with Facebook audience network. My problem is I don't know where i can add my App ID. I used this Plugin by Raymond Xie:

Name: FacebookAdsPluginPro

Plugin ID: com.rjfun.cordova.facebookads

https://github.com/floatinghotpot/cordova-plugin-facebookads

I Added this Plugin to Intel XDK. However, the mediation thing is not working because the App Id is missing

Dose anyone know How I can add it.

Note: When I click on FacebookAds plugin in Intel XDK. There is something by the version called "change version or variables" dose this solve my problem ?

Thank you for your time.

Anyone
