Freshtogo Android app connect with facebook business manager dataset

I am looking for a Freelancer who can help me integrate my Freshtogo Android app with Facebook Business Manager dataset. We have connected our app with business manager but won't be able to track any event from Facebook event manager. The main purpose of this integration is to track app installations and usage & target specific audiences for future ads. The app does not require any additional features for the integration and the data that will be available after the integration is complete is ad performance.
