I'm encountering an error when trying to access the direct_deals_tos_accepted field via the Facebook API. The error message is as follows:

{ "error": { "message": "(#3) Ad Account must be on whitelist", "type": "OAuthException", "code": 3, "fbtrace_id": "Anvl54TGsVXyaipw2cHNSnQ" } }

Can anyone explain what this error means and how I can resolve it? Specifically, I need to understand the following:

1. What does it mean for an ad account to be on a whitelist?

2. How can I get my ad account whitelisted to access the direct_deals_tos_accepted field?

3. Are there any specific steps or contact points within Facebook that I need to follow to request this whitelisting?

4. Is there any additional information or permissions that might be required for this access?

Any guidance or detailed steps would be greatly appreciated!
