Meta Ads + RevenueCat + Conversion API: Which Setup Correctly Tracks Free Trial Activations?

We are running Meta paid ads extensively.

Currently, we

• Able to track number of install accurately.
• NOT ABLE to track free trial activation accurately.

We would like to solve the above issue, by using RevenueCat + Meta Conversion API.

Can someone from RevenueCat, confirm which is the correct changes, so that we can track both install and free trial activation accurately?

Before using RevenueCat + Meta Conversion API.

    Info.plist
        <key>FacebookAutoLogAppEventsEnabled</key>
        <string>TRUE</string>

        <!-- In-App Purchase Automatically Logged Events -->
        <!-- https://developers.facebook.com/docs/app-events/getting-started-app-events-ios/ -->
        <key>SKIncludeConsumableInAppPurchaseHistory</key>
        <true/>

    AppDelegate.swift
        private func initFacebook(_ launchOptions: [UIApplication.LaunchOptionsKey: Any]?) {
            // https://developers.facebook.com/docs/app-events/getting-started-app-events-ios
            ApplicationDelegate.shared.application(
                application,
                didFinishLaunchingWithOptions: launchOptions
            )
        }

        func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

            ...
            initFacebook(launchOptions)
        }

After using RevenueCat + Meta Conversion API, should we use Version A or Version B?

Version A:

    Info.plist
        <key>FacebookAutoLogAppEventsEnabled</key>
        <string>FALSE</string>
        
        <!-- In-App Purchase Automatically Logged Events -->
        <!-- https://developers.facebook.com/docs/app-events/getting-started-app-events-ios/ -->
        <key>SKIncludeConsumableInAppPurchaseHistory</key>
        <false/>

    private func initFacebook(_ launchOptions: [UIApplication.LaunchOptionsKey: Any]?) {
        // disable automatic tracking
        FBSDKCoreKit.Settings.shared.isAutoLogAppEventsEnabled = false

        // optional: call activateApp
        FBSDKCoreKit.AppEvents.shared.activateApp()
        
        // https://developers.facebook.com/docs/app-events/getting-started-app-events-ios
        ApplicationDelegate.shared.application(
            application,
            didFinishLaunchingWithOptions: launchOptions
        )
    }

Version B:

    Info.plist
        <key>FacebookAutoLogAppEventsEnabled</key>
        <string>FALSE</string>
        
        <!-- In-App Purchase Automatically Logged Events -->
        <!-- https://developers.facebook.com/docs/app-events/getting-started-app-events-ios/ -->
        <key>SKIncludeConsumableInAppPurchaseHistory</key>
        <false/>

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        ...
        initFacebook(launchOptions)
    }

    private func initFacebook(_ launchOptions: [UIApplication.LaunchOptionsKey: Any]?) {        
        // https://developers.facebook.com/docs/app-events/getting-started-app-events-ios
        ApplicationDelegate.shared.application(
            application,
            didFinishLaunchingWithOptions: launchOptions
        )

        // disable automatic tracking
        FBSDKCoreKit.Settings.shared.isAutoLogAppEventsEnabled = false

        // optional: call activateApp
        FBSDKCoreKit.AppEvents.shared.activateApp()
    }

Thank you.
