I need to retrieve the questions information used in a Brand Lift study through the API.

While experimenting with the Graph API Explorer, I found the "questions" field within the "brand_requests" endpoint. However, when I attempt to make the call, I receive the error "(#10) Application does not have permission for this action" (screenshot attached).

I've searched the documentation but couldn't determine the necessary permission to make this call successfully. I've checked the following documentation:

• https://developers.facebook.com/docs/marketing-api/reference/ad-study-objective/
• https://developers.facebook.com/docs/marketing-api/reference/ad-study-objective/brand_requests/

I would like to know if it's possible to obtain this question information, if I'm using the correct endpoint, and which permission I need to make this call.

Thank you.
