I am trying to access users' profile pictures through the WhatsApp Business API by using the endpoint to retrieve profile details. However, the API response does not include the "profile_pic" field, even when the user has a public profile picture.

I have confirmed that I have the necessary permissions (whatsapp_business_messaging) and am using the latest version of the API. Additionally, I have tested this with different phone numbers, but the issue persists. Could you please inform me if there are any additional requirements or specific configurations needed to access users' profile pictures?

Thank you for your assistance.
