How do I test Apple's new Search Ads Attribution API?

Here is the code I'm using. How can I test `attributionDetails` from Apple so I can ensure my Search Ads Attribution API code is working properly? Apple provides little to no details (https://searchads.apple.com/help/measure-results/#attribution-api) on how developers can do some test dummy conversions for testing.

    {
        if ([[ADClient sharedClient] respondsToSelector:@selector(requestAttributionDetailsWithBlock:)])
        {
            // iOS 10 call exists
           
            [[ADClient sharedClient] requestAttributionDetailsWithBlock:^(NSDictionary *attributionDetails, NSError *error) {
                if (error) {
                    NSLog(@"Request Search Ads attributes failed with error: %@", error.description);
                   
                    if (error.code == ADClientErrorLimitAdTracking) {
                        NSLog(@"Limit Ad Tracking is enabled for this device.");
                    }
                }
                else {
                    NSLog(@"Search Ads attributes: %@", attributionDetails);
                   
                    // Found details, track the purchase.

                    // Check value for "iad-attribution":
