react-native-fbsdk-next Custom data in Params not appearing in Events Manager

Question

I have an issue sending custom parameters to the Facebook Events Manager using the library react-native-fbsdk-next.

I can see the events coming in, but they don't have any parameters.

Here is the example of how I send the data:

 const payload: Params = {
        screen_class: 'home',
        screen_name: 'home',
      }

      // Facebook analytics
      AppEventsLogger.logEvent('test_event1', payload)
