Facebook Login Permissions Overhaul

I am seeking a skilled developer to modify user permissions within the Facebook login flow for my business. The key change I wish to implement is gaining access to the user's business_arrangement. This will facilitate improvements in my business processes. Consequently, the freelancer must be adept at understanding and navigating Facebook's API and user permission settings. Proficiency in social login options integration should be shown, alongside proven capacity in problem-solving and business process enhancement. Possessing prior experience in similar projects will be highly desirable.
