I'm developing an application to capture leads from a Facebook lead form. Here's what I've done so far:

1. I created an App in the Facebook Developer Dashboard.
2. I verified the webhook for this app, and the verification was successful.
3. I have obtained advanced access for the following permissions: leads_retrieval, pages_show_list, pages_manage_metadata.
4. I have enabled the User object and subscribed to leadgen events.
5. I tested the webhook, and it's sending test leads in the response as expected.
6. My app is in Live mode.

However, when a real lead is created on Facebook, I'm receiving the following response instead of the actual lead data:

{   "entry": [     {       "id": "0",       "time": 1724921046,       "changes": [         {           "field": "leadgen",           "value": {             "ad_id": "444444444",             "form_id": "444444444444",             "leadgen_id": "444444444444",             "created_time": 1724921046,             "page_id": "444444444444",             "adgroup_id": "44444444444"           }         }       ]     }   ],   "object": "page" } 

What could I be doing wrong, and how can I start receiving real lead data instead of this mock response?
